>>> BACK NOW WITH OUR SERIES, "A.I. REVOLUTION," AND IN FOCUS TONIGHT, JOBS, HOW THEY'RE PERFORMED, HOW THEY'RE CHANGING, AND THE POTENTIAL RISKS THAT A.I. POSES TO THEM. TO FIND OUT, JAKE WARD WENT TO THE NATION'S LARGEST PRIVATE EMPLOYER. >> Reporter: ONCE UPON A TIME JOSE AVILA HAD TO HAVE AN INCREDIBLE MEMORY. WHEN YOU STARTED WERE YOU SUPPOSED TO HAVE MEMORIZED WHERE EVERYTHING IS? >> YES. >> Reporter: AND GREAT SHOES. >> SO I WOULD HAVE TO ACTUALLY TAKE THEM TO THE ITEMS THAT THEY NEEDED, SO FROM ONE END OF THE STORE TO THE OTHER. >> Reporter: BUT TODAY AN A.I. POWERED APP SHOWS WHERE EVERYTHING IS AND NEEDS TO GO. >> IT'S MAKING MY JOB MUCH EASIER. >> Reporter: WALMART IS ALREADY A COST-CUTTING MACHINE, AND YET THE COMPANY WANTS TO BE EVEN MORE STREAMLINED. SANJAY IS IN CHARGE OF MAKING THAT HAPPEN. HOW CAN YOU POSSIBLY GROW MORE EFFICIENT THAN YOU CURRENTLY ARE? >> JAKE, THAT'S WHERE TECHNOLOGY WILL PLAY A KEY ENABLING ROLE. WE ARE TRANSFORMING OUR SUPPLY CHAIN AND OUR STORE OPERATIONS. >> Reporter: AND AS WE SAW IN THIS CALIFORNIA SUPERSTORE, A.I. IS HOW THEY PLAN TO DO IT. WHEN TRUCKS ARRIVE TO BE OFFLOADED, A.I. HAS ALREADY ORGANIZED THE PALLETS INSIDE. IT LOOKS DISORGANIZED TO ME, BUT IF I UNDERSTAND CORRECTLY, A.I. IS TELLING YOU THROUGH THE PHONE WHERE EVERYTHING IS AND WHERE IT SHOULD GO. >> YES, WE HAVE TO OPEN UP OUR CAMERA AND HOLD UP OUR WORK DEVICE, AND THEN IT'S GOING TO TELL US WHAT BOXES NEED TO GO OUT. >> Reporter: SENSORS IN EVERY AISLE SPOT THINGS AS SMALL AS A OPEN, AND EVEN A.I. ARRANGES THE SHELVES. >> THEN WE CAN LEARN AND SAY, OKAY, DOES THIS DO BETTER THAN PUTTING ANOTHER BRAND OR FLAVOR IN THERE? >> Reporter: WALMART IS THE NATION'S LARGEST PRIVATE EMPLOYER, AND WHAT THEY DECIDE TO DO WHEN IT COMES TO EFFICIENCY SETS NATIONAL STANDARDS, SO WHEN THEY DECIDE TO ADOPT A.I., IT HAS IMPLICATIONS FOR THE WHOLE COUNTRY, AND THAT, OF COURSE, RAISES A CRUCIAL QUESTION FOR WORKERS. DOES A.I., DO YOU THINK, FORECAST A WORLD IN WHICH YOU WON'T NEED AS MANY HUMANS IN THE STORE? >> WE VIEW TECHNOLOGY AS HELPING OUR ASSOCIATES DO A PHYSICALLY DEMANDING JOB AND HIGH-SKILLED JOB ROLES, SO OVER TIME WE BELIEVE THAT WE'LL BE ABOUT THE SAME OR MORE NUMBER OF ASSOCIATES IN THE COMPANY. >> Reporter: AS A RETAIL WORKER, CAN I SORT OF RELAX ABOUT MY JOB IN THE FUTURE, DO YOU THINK? >> NO, I DON'T THINK THAT YOU CAN. >> Reporter: EXPERTS SAY THE NUMBER OF JOBS MAY REMAIN THE SAME, BUT PEOPLE WITHOUT THE RIGHT SKILLS WON'T GET THEM. >> THERE ARE INCREASING FRICTIONS IN THE WORKPLACE SUCH THAT IT IS HARDER FOR WORKERS TO TRANSITION FROM ONE JOB TO A NEW JOB. >> Reporter: AVILA, THE STORE LEAD, SAYS WORKERS HERE ARE HAPPIER IN THE AGE OF A.I. >> HEAD COUNT AND OUR TURNOVER IS MUCH BETTER THAN TWO YEARS AGO. >> R
