But, I'm sure the people who wrote the book mentioned in the article can rest easy: creativity, knowledge, and originality are still valuable, and LLMs are not (yet) able to reproduce those.
But this "access to the world" needs massive scale, we are billions of humans all experiencing the world, AI needs probably a similar number of agents doing massive trials and search. AlphaGo sure did need lots of self-play games, not just a couple. AlphaTensor learned to improve matrix multiplication by the same method. Biological evolution produced us the same way.
It's an open-ended exploration problem. A closed system can't do it, and the scale needed makes it expensive.
