Bezos's Prometheus raises $12B for physical-world AI

Jeff Bezos's startup Prometheus has closed a $12 billion funding round to build what it calls an 'artificial general engineer' — AI designed to automate heavy engineering tasks and drug design in the physical world, not just software. The round values the company at $41 billion, making it one of the most expensively backed AI bets of the decade. It arrives the same week that modular factory-robot startup Theker raised $85 million on a similar thesis that general-purpose physical AI is the next frontier.
