Elon Musk said AI could usher in an "age of amazing abundance" for humanity. The SpaceX CEO has previously warned about AI's potential risks, including "killer robots annihilating humanity." Elon Musk says humanity probably shouldn't hit the brakes on artificial intelligence — even if it could. "I can't see any way to really stop this incredible momentum of AI and robots." Musk has long paired warnings of AI catastrophe with predictions that have increasingly blended in more optimism.
