Elon Musk: 'In the future, robots will produce an enormous number of robots, and they will meet all human needs. This means that at some point, you won't even be able to think of anything else to ask from robots because goods and services will be extremely abundant. The number of robots will surpass humans. I believe everyone on Earth will have a humanoid robot because you'll want a robot to look after your kids, take care of your pets, and care for your elderly parents.' I'm very optimistic about the future. I think we're heading toward a future of extreme material abundance, and that's amazing. We're undoubtedly living in the most exciting era in history.
