The Future Of Humanity With Dr. Michio Kaku

if somebody gives you from up high the meaning of life it's too easy we have to reinvent ourselves that the meaning of life is rediscovery so you see physics not only unlock the secrets of the universe it also predicts the future so that's what we physicists do we invent the future ladies gentlemen professor Michio Kaku [Applause] well after such a great introduction I can't wait to hear the speaker myself first of all I have a confession to make you see sometimes all these honors and accolades can backfire on you recently New York Magazine had a contest who are the 100 smartest most intelligent people in New York well I'm proud to say I made the list I'm now officially one of New York's 100 smartest people but in all fairness in all fairness I have to admit that Madonna also made the same list and next year they tell me that Lady Gaga is gonna push me off the list entirely you know I've had the privilege and the honor of interviewing over 300 of the world's top scientists who are inventing the future in their laboratories and whenever I interview these scientists about the future I ask them the key question the question of all questions the question that has haunted theologians and philosophers for generations that question is is there intelligent life on the earth well I was watching the Kardashians on TV last night and I'm now convinced scientifically there is no intelligent life on this planet nope no chance well people come up to me and they say professor what does the physicist do anyway well we physicists like to invent things we invented the transistor which makes possible the computer we invented the laser which makes possible the Internet we wrote the world wide web the world wide web was written by physicists to keep track of subatomic particles and don't forget in your living room we invented television we invented microwaves radar we invented in a hospital the x-ray machine we invented the MRI scan and don't forget we also invented the space program and the GPS satellites now whenever we invent something we make a prediction when we helped to invent the world wide web one physicist predicted that the internet would become a forum of high culture high art and high society well today we know that 5% of the Internet is pornography but that's because teenage boys log on to the Internet just wait until the grandmas and grandpas log on to the Internet then 50% of the internet could become pornography so in my books I try to summarize what these top scientists have told me and speaking about the space program which I write about in my latest bestseller we have to remember that the dinosaurs the dinosaurs did not have a space program sorry about that that's why they're not here today we do have a space program and we're entering the second golden era of space exploration when costs keep plunging down for example how many people here in this room raise your hand how many people in this room have seen the movie the Martian starring Matt Damon Wow most of you well that movie cost a hundred million dollars but the Indian government sent a probe past Mars for seventy million dollars a Hollywood movie about going to Mars costs more than actually going to Mars so that's the changing dynamics of space travel that I'll talk about more in a moment in my previous best-seller physics of the future I talked about artificial intelligence computers of the future the Internet of the future what will the Internet look like I predict that the Internet of the future will be so small it'll be in your contact lens you will blink and you will be online and who are the first people to buy Internet contact lenses college students taking final examinations they will blink and they will be online and your contact lens will also recognize people's faces you'll always know who you're talking to and if they speak to in Chinese or Greek no problem your contact lens will translate Chinese Greek into any language you want this is very handy let's say tonight you're at a cocktail party and there's some very important people at that cocktail party but you don't know who they are in the future you will know exactly who to suck up to at any cocktail party and this could be very handy on a blind date let's say your blind date says that he's single he's rich and he's available but your contact lens says that no he three times divorce has paid child support payments and he's dead broke so these could be very important in the future in my other book physics of the impossible I talked about time travel starships when will we have teleportation to the Stars and I answer the question what happens if you enter a time machine and you go back back into the past and you meet your mother when she was a teenager and she falls in love with you well if your mother falls in love with you when you're at before you were born you're in deep doo-doo if that happens and my other bestseller the future of the mind I talk about the incredible developments that we physicists have made by probing probing into blood flow of the living brain did you know that we can now record memories this is amazing the first memories were recorded two years ago and can be sent on the Internet in other words the future of the internet will be brain net whilst and emotions feeling sensations on the Internet not just type teenagers will love it teenagers but happy faces at the end of every sentence why not put the emotion after the end of every sentence and by looking at the physics a blood flow in the thinking brain we can actually see thoughts thoughts as they're created in the living brain and we can also show that certain old wives tales are actually true for example this an old wives tale that says that when a man talks to a pretty girl he starts to act stupid absolutely true when you brain scan a man talking to a pretty girl blood drains from the prefrontal cortex and he starts to act mentally [ __ ] absolutely true we can men we can measure this effect now rather than simply gossip about it now people come up to me and they say professor how did you as a child get interested in theoretical physics most children want to become like an astronaut or a fireman I wanted to become a theoretical physicist what happened well what happened was when I was 8 years old something happened which changed my life my teachers were talking about the fact that a great scientist had just died and I still remember they published a picture in the evening newspaper a picture that I will never forget a picture which changed the destiny of my life that picture was a picture of his desk and the caption said this is the unfinished manuscript from the greatest scientist of our time and I said to myself well why couldn't he finish it it's a homework problem right why didn't he ask his mother what could be so hard that you can't finish it well I went to the library and I found out the man had a name his name was Albert Einstein and that picture was a picture of his unfinished unified field theory he was looking for an equation no more than one inch long that would allow us to quote read the mind of God and I said to myself wow that's for me that's what I want to work on for the rest of my life to complete that book and when I was in high school I pursue this when I was in high school in fact I built an atom smasher in my mom's garage at 2.3 million electron volt betatron particle accelerator in my mom's garage I went to my mom one day and they said mom can I have permission to build an atom smasher in the garage and she said sure why not and don't forget to take out the garbage so I assembled 400 pounds of Transformers Steel 22 miles of copper wire and I created a six kilowatt 2.3 million electron volt meter's one particle accelerator in the garage finally it was ready I plugged it in I heard this huge crackling sound is all the energy surge through the magnets and then I heard this pop-pop-pop son as I blew out all the circuit breakers in the house the whole house was plunged in darkness you know my poor mom she come home from a hard day's work and say to herself okay where's the fuse box and why couldn't I have a son who plays baseball maybe if I buy him a basketball and for God's sake why can't he find a nice Japanese girlfriend I'm here why does he have to build these machines well then I went to college and I learned that there was a crisis in physics every time we smashed a proton we found more particles pi massan's leptons neutrinos hundreds hundreds of particles every time we smashed a proton apart in fact J robert Oppenheimer the father of the atomic bomb made an official announcement he said that this year the Nobel Prize in Physics should go to the physicist who does not discover a new particle this year well today we think we can make sense out of all these particles we think that these particles are nothing but musical notes on a tiny rubber band think of a rubber band when it vibrates like this we call it an electron but it could also vibrate like this we called it on the tree Noam you could also vibrate like this and it's called a quark you vibrating enough ways and it gives you all the subatomic particles of the universe so what are particles particles are nothing but musical notes on a tiny tiny vibrating string what is physics physics is the harmonies the harmonies you can make on vibrating strings what is chemistry chemistry is the melodies you can play on strings what is the universe the universe is a symphony of strings and then what is the mind of God the mind of God is cosmic music resonating through hyperspace that is the mind of God and if you want to know more about this by my book but today let us talk about humanity itself in our destiny in outer space first of all it all starts with this man Robert Goddard a man who defied convention he built the first liquid-fuel rocket out of his own pocket people ridiculed him they thought he was a phony a fake the New York Times issued an editorial denouncing this man calling him a total fake because quote Rockets cannot move in a vacuum unquote wrong this is the father of all rocketry and why why did this man persist on building the first rockets when everyone was laughing at him the reason is when he was a child he read a book that book was War of the Worlds by HT Welles and this young boy was hook he said to himself that's what I want to become a rocket scientist just like what you see in War of the Worlds and there was another gentleman by the name of Carl Sagan the astronomer when he was a child he also read a book that book was John Carter of Mars a fiction book about a man who can somehow leap to the Red Planet and become a Superman now more recently there was another teenager who read a book by Isaac Asimov the foundation series which I read as a child about Earthlings becoming a multi-planet species that man was Elon Musk and he became a billionaire and he's now created a fleet of rockets to fulfill the dream that he had as a child and that is to lay the foundations for a multi-planet civilization and why bother because one day we will have to the earth this is a law of physics how will the earth die in fire or ice five billion years from now the earth will be eaten up by the Sun on a scale of fifty million years we have to worry about asteroid collisions on a scale of ten thousand years we have to worry about ice ages on a scale of decades we have to worry about global warming and nuclear proliferation this is how the dinosaurs died and whenever I see this picture I say to myself what was this dinosaur thinking looking up in the sky seeing this huge rock five miles across come whizzing across the horizon what was going on in that dinosaurs mind I said to myself the dinosaur on the left he was probably saying to himself this is gonna really ruin my day and the dinosaur on the right is probably saying oh [ __ ] well that's what happened to the dinosaurs and it was good for us because we could then repopulate the earth but speaking about that seventy thousand years ago seventy thousand years ago something happened which almost wiped out Homo sapiens it's amazing every every time I think about this I realize that 70,000 years ago only a handful of us a handful of us survived this catastrophe how many we can calculate the number a few hundred think about it for a moment 70,000 years ago a volcano we think like the volcano in Yellowstone in the United States erupted wiped out most of Homo sapiens leaving only a handful maybe a hundred maybe a thousand humans that would then populate the entire earth so we need a back-up plan we need Plan B we need an insurance policy to make sure that this doesn't happen to us now I'm not saying that we should evacuate the earth or abandon the earth now it's too expensive but we need an insurance policy and is skating cheaper and cheaper every year as I said before Elon Musk a private individual is building his own rocket ship to the moon and to Mars I predict that our grandchildren will be able to honeymoon on the moon prices are dropping like a rock honeymooning on the moon in fact we have not one not two but three three moon rockets capable of going to the moon nASA has the SLS Elon Musk has the Falcon Heavy and Jeff Bezos richest man on earth founder of Amazon has the new Armstrong rocket this is the beer farm it may eventually take us to Mars already a Japanese billionaire has bought tickets tickets to go to the moon on the bfr this is a historic rocket now what does VFR stand for B stands for big R stands for rocket and F stands for whatever you want now some people say that maybe we'll encounter alien life in outer space once we go to the moon and on to Mars I don't know however I'm on radio some people call me on radio and they say professor I know the aliens are out there because I've been kidnapped I've been abducted I've been on their flying saucers well I have a word of advice the next time you are kidnapped by a flying saucer for God's sake steal something I don't care if it's an alien ship an alien paperweight steal anything because there's no law against stealing from an extraterrestrial civilization no law whatsoever and just remember you then you'll have bragging rights you have proof proof of what actually happened now I'm gonna close in the following comment and then we're going to open it up for discussions first of all when I was a child a very young kid I had a role model my role model was Albert Einstein and my favorite Einstein story is this when Einstein was an old man he was tired of giving the same talk over and over again so one day his chauffeur came up to him and the chauffeur said professor I'm really a part-time actor I've heard your space so many times I've memorized it so why don't we switch places I will put on the mustache I will put on the wig I will be the great Einstein and you can put on my jacket and be my chauffeur well Einstein loved the joke so they switched places this went along famously until one day a mathematician in the back asked a very difficult question and Einstein that off the game is up but then the chauffeur said that question is so Elementary that even my chauffeur here can answer it for you thank you very much thank you very much and we'll now have a discussion and Q&A thank you so much for peso Kaku so before we let everybody else have their say I'm lucky enough to get first dibs so I read your book and one of the things that I found really fascinating was your discussion of artificial intelligence recently there's been a lot of discussion about whether or not artificial intelligence is going to save everyone or doom us all and I was wondering if you could maybe tell us a bit more about that well I think we've been brainwashed by Hollywood into thinking that Arnold Schwarzenegger is gonna come after us in a terminator outfit and destroy humanity let's look at the facts one of our most advanced robots is called azimu you've seen him on television as the mow can run walk jump climb up stairs and even dance he dances much better than me in fact and I had a chance to interview the creator of the world's most advanced robot for BBC television and I said to himself compared to an animal how smart is the world's smartest robot he was very honest he said his creation as ammo' has the intelligence of a cockroach a stupid cockroach a [ __ ] stupid cockroach so I have a really really terrible cockroach yes this is not comforting but as the years go by I said to myself eventually it'll be as smart as a mouse then as smart as a rat then as smart as a rabbit smart as a cat or a dog and then smart as a monkey by the end of the century they could become dangerous because monkeys know they are monkeys robots do not know they are robots but monkeys know they are monkeys now dogs on the other hand dogs are confused dogs think that we are a dog we're the top dog and they're the underdog but monkeys they're not confused at all I think when our robots become as smart as a monkey with self-awareness we should put a chip in their brain to shut them off if they have murderous thoughts easy as that right yeah for a while another hundred years I think before robots become that smart okay good to know so speaking of science fiction you're a fan I'm a fan and we were having a chat earlier about some things on which we disagree do you want to go into that yes well first of all whenever I watch a science fiction movie my first reaction is I cringe I calculate how many laws of physics they violated in the last 15 minutes but then I say to myself now wait a minute this is supposed to be fun it's supposed to be fiction you see when I was a child I actually had two role models the first role model was Albert Einstein because I went wanted to complete what he couldn't complete which we think we can do now with string theory but I but on Saturday mornings I used to watch Flash Gordon on television and I was hooked I mean Reagan's invisibility shield cities in the sky what's there not to love with Flash Gordon so whenever I watch science fiction I cringe but then I say to myself now wait a minute children are watching the same movie they don't know the laws of physics but they love science as a consequence so I say to myself okay if HT Wells could inspire Goddard and if edgar rice burroughs of tarzan could explore it could inspire Carl Sagan all power do them so I think that even if I have to cringe that's the price you pay look I'm not I'm not disagreeing but you have to admit that when you hear things like it's the sphere of pure energy a little bit of you dies inside yes so we're just saying that it's to sacrifice this is dying a little bit generations of scientists and progress the humanity yeah but you know I speak to scientists a lot and I asked them how many people in the audience as children were inspired by Star Trek and a lot of them were NASA scientists and a lot of them raise their hand and say that yeah when they were kids Star Trek pave the way for them to become a NASA scientist so that's the price we pay fair enough sir what meets your standard what would you say is good science fiction then well one of my favorite science fiction movies is the movie 2001 the only thing wrong was they got the date wrong 2001 no 2,100 2,100 we'll have thinking robots well has spaceships to Jupiter but you see that movie was very interesting because the aliens usually have makeup on them like on Star Trek they have makeup on their noses and they're just actors but in 2001 the aliens are well they have robots that are self-replicating they can make copies of themselves and that is the most efficient way to explore the galaxy forget Captain Kirk forget the enterprise there are too many planets out there you take a robot and it lands on the moon makes copies of itself as in the movie thousands of copies which then go out and make more copies and then you have an exponential explosion of robotic probes that colonize the Milky Way galaxy in a hundred thousand years now who else does that mother nature mother nature has a virus which lands on yourself makes hundreds of copies of itself which land on other cells makes more copies and then in two weeks you start to sneeze amazing a molecule can cause you to sneeze in two weeks that's the way to colonize the galaxy self-replicating robots and it's all in the movie 2001 sir aim is to be a sort of cosmic cold yeah inspiring well what about you I'm sure there's some movies that make you cringe I have thoughts about interstellar yes there was no way that should have been a manned mission the planet was definitely inside the sports child radius and love is not the strongest force in the universe whole rant perhaps another time but the black hole was absolutely beautiful and that's actually what frustrated me because they got all the hard stuff right and I loved a circular wormhole that was that was amazing but actually that that actually did get me thinking and and again sort of thinking back to your book one of the things I really loved and this is the great thing about science fiction I think is that you can paint a picture of something that's far in the future and far beyond what we can do right now and you look at something like that and you think how could we possibly get there we have here's where we are that's what's over there and you can't see the connection and when I was reading your book I would often find you would open with an idea that you know sort of laser teleportation that made me sort of think really you know I was with you a long year but really are we going to get there but then you would bring it back and talk about what we actually have today and then really take me through logically how we could make these incredible advances and I thought that was really fascinating I'd love to hear more one example is that Isaac Asimov wrote about us being pure energy rocketing through outer space at the speed of light as pure energy and when I read that I said to myself that's stupid I mean how can we become pure energy and explore the galaxy and then I realize it is possible because one day we will digitize the human body digitize our memories digitize our brain cells and all that information will create a carbon copy of ourselves it will be immortal you go to the library and instead of taking a book about Winston Churchill you'll talk to Winston Churchill because he's been digitized I would love to talk to Einstein I would love to sit down and talk to him because he's been digitized everything known about him has been digitized so we take this information put a laser beam and shoot it to the moon in one second you're on the moon no booster rockets no accidents in 20 minutes you're on Mars in six hours you're on Pluto in four years you're on the nearby stars and let me stick my neck out I think this already exists I think aliens and out of space they don't deal with flying saucers that's so 20th century now they don't deal with booster rockets and meteorite impacts an accident weightlessness although all the horrible things about space travel no they digitized themselves shoot their consciousness at the speed of light across an intergalactic laser highway and if there's a laser highway next to us we are too stupid to even know it we don't even have the instruments capable of detecting a laser highway where billions of souls rock it at the speed of light throughout the galaxy so you're right we are kind of stupid but where does that leave us with the ethics of all of this so thinking about something like implanting memories I mean as he said there are all sorts of incredibly cool applications of that but it's also a little bit uneasy making yes as I mentioned two years ago in mice the first memories were recorded and then played back and the mouse remembered something that they did months earlier now we're doing it on primates at Emory University and also in Los Angeles next we'll be Alzheimers patients so an Al's I Marissa patient will push a button and then memories memories come flooding into their hippocampus they remember who they are now at MIT they even inserted the first false memory into a mouse that raises all sorts of ethical considerations because one day you will go to the the CD store or video store and you'll get that vacation that you never had however it has to be clearly marked this vacation is fake you never went to Cancun you never went to Hawaii but what happens if you remove that then memories could become all mixed up and the police are gonna have a hard time eyewitness accounts of memories can be trusted anymore so I think we have to be very careful it's a very powerful technology but brain net is coming because we can already tape record certain memories and some people think that one day we learned calculus well they're in calculus by pushing a button and having all that knowledge put into our mind just like the movie matrix remember the movie The Matrix where life itself was an illusion in fact let me ask you guys a question let me ask you a question how many of you people out there late at night just before you go to sleep how many people here have had that weird feeling that maybe just maybe life is an illusion like in the movie The Matrix then you're the only real person raise your hand raise your head if you're happy now I do oh my god you guys are crazy I'm gonna room with all these crazy people how can you be the only one in the universe when I'm the only one in the universe I'm actually in New York right now just about to go to sleep having my memories uploaded come on give me a break well so now we're all thoroughly terrified but you still sir you're still pretty optimistic though about where we're going and how we're going to get there how do you stay that optimistic when I encounter people many people are pessimistic about the future and I tell them that's because there's a gene a gene for pessimism because our ancestors were pessimistic they were cautious because our ancestors our ape ancestors who were not cautious died because they took too many risks and those genes never spread so I think there is a pessimism gene but I think history is made by the optimists as General Eisenhower once said wars are won by optimist never pessimists pessimist dunno make history but on the other hand science you see there's no gene for science we're not born with a gene for science we are born I think with a gene for gossip for jumping to conclusions for making up stories I think there is a gene for that but there's no gene for science and so I think that optimism scientific outlook is an acquired taste that you have to develop a feel for it now my personal attitude is the smallest unit of history is the decade anything smaller than a decade you get random fluctuations and when you look at history decade by decade then you realize the enormous progress that we've had I mean my grandparents lived in a world where high-speed travel was getting stuck in the mud with your wagon and long-distance communication was yelling out the window and life expectancy was about 45 years of age you know what they say life is short you're born you go up and then you die life's a [ __ ] well yeah life is a [ __ ] but then came science now we can live into our 70s and 80s now we have high-speed travel we have the Internet we've opened up new worlds to mess up so inspiring I like life is precarious eat dessert first so you see us keeping going and I really like the discussion of the type one civilization that's sort of on our horizon perhaps you could talk a bit more about that when we physicists looking at a space we know they're out there there's so many stars so many galaxies out there but we don't talk about little green men we like to rank things by energy that's what we physicists do we give numbers and rank things by energy so a type one civilization is planetary they control the weather they control the atmosphere they control Epis fear a geologic phenomenon on their planet that's called type one sort of like Flash Gordon and Buck Rogers then this type - a type two civilization is stellar they control the output of an entire star like Star Trek the Federation of Planets is a typical type to civilization then this type three galactic and these creatures roam the Galactic space lanes they play with black holes they roam the galaxy like star wars star wars would be a typical type three civilization now on this cosmic scale what are we are we type one that played with the weather are we type two the play with the Stars are we type three that play with the galaxy no we're type zeros we don't even write on this scale we get our energy from dead plants oil and coal however I think we are about a hundred years away from type one take a calculator you can calculate them we're about a hundred years away from type one for example what is the internet the internet is the beginning of a planetary telephone system is the first major type one technology to fall into our century the Internet and take a look at the language what language will this type one civilization speak on the internet already we know that English and Mandarin Chinese are the two dominant languages on the internet and take a look at sports entertainment sports we have the Olympics we have soccer take a look at fashion we have Gucci Chanel we have a planetary music being developed it's called rock and roll and rap music oh my god so we're talking about a planetary culture being created right before our eyes and I think by 2100 we will become a type one civilization a planetary civilization unless we really mess it up that could also happen so if the Internet is our first type one technology do you have any any ideas about what the second might be that I don't know however if I if I couldn't know I would become a billionaire and it wouldn't be here right now I'll be out there vacation exactly so we've got just over five minutes to go so I thought we just do something really nice and easy and talk about what you think is the most exciting technology on our horizon maybe it isn't going to be the second Technol technology of a type one civilization but we're in this period of extraordinary and exciting change so what are you looking forward to well the two greatest problems in all of science is to understand the very very big that is the creation of the universe and also the very very small where does the waited life come from where did consciousness come from and there's so many things we don't know like looking at the cosmos we realize that every high school textbook is wrong every high school textbook says the world is mainly made out of atoms nope it's made out of dark matter and dark energy there's a Nobel Prize a Nobel Prize waiting for the person who figures out what is dark matter which is invisible and dark energy which drives the Big Bang and if any of you if any of you ever figure out what dark matter or dark energy is be sure to tell me first we'll split the nobel prize money sir we're looking forward to scientific achievement but technologically any I mean one thing that sort of makes me sad I think honestly and I don't know why I'm ending on a pessimistic note is I feel like I was born 50 years too early for this second space age and you just think about the way that space is being democratized and commercialized and the accelerating pace of change and it does make me wish that I could live longer and see it speaking of living longer I think immortality or a form of immortality is possible in the coming decades two kinds of immortality first is genetic biological immortality of just living longer and the second is digital immortality because already in Silicon Valley they're companies offering to digitize everything known about you your credit card records your Instagram pictures everything known about you digitized and the connectome project will map the entire brain just last month scientists were able to digitize the brain of a fruit fly a fruit fly is a hundred thousand neurons we've now digitized every single one and we know the architecture of the brain of a fruit fly a hundred thousand neurons we have a hundred billion neurons up here and that could be digitized by the end of the century and then will become immortal we'll be able to duplicate your emotions your feelings everything then the next question is well is that really you well to paraphrase Bill Clinton it all depends on how you define you if you are a biological entity then this immortality is like a tape recorder but if you is a sum total of all your dreams feelings memories all your desires if your soul if your soul can be reduced to information then you can live forever so one day in the library your great great great great great grand is we'll want to talk to you and you'll talk to your great-great-great great-great grandkids digital immortality the other immortality is biologic immortality and we're making enormous strides in that area as well for example aging where does a car age the most well a car age is the most in the engine that's where you have combustion and moving parts what is the engine of a cell the mitochondria so we know know where ageing takes place in the cell the mitochondria and then one day will digitize millions of old people digitize millions of young people and look where all the mistakes are and then use genetic engineering to cure those mistakes so I think that a form of immortality is not too far off in the distance and we do you up to be digitized if you had the choice Oh would I want to have a chance at being immortal well why not I mean I got ever there's a Greek myth the the tale of poor Tiffany's once upon a time there was a Greek goddess Aurora who fell in love with a mortal human being called Tiffany's she asked the god Zeus for eternal life for the boyfriend because she was immortal but the boyfriend was not so Zeus gave the human boyfriend the gift of immortal life but you see Aurora made a huge mistake a huge mistake she forgot to ask for eternal youth as well as eternal life so every year her boyfriend got older and older she was immortal she was young forever but the poor boyfriend so I think that when we have the secret of eternal life we should also have the secret of eternal youth to go with it uh sir this has been absolutely a huge honor for me and thank you for inspiring me years ago and it's incredible to be here now and to hear you speak but I think I speak for everyone here when I say that that was absolutely inspiring and I am full of hope and excitement to see what happens Thanks so thank you very much professor Kaku [Applause] [Music] [Applause] [Music] [Applause] [Music] [Applause] [Music]

Awesome book.. front to back..
