If we and up following this approach, it is clear that it will be combined with some sort of virtual-world building, where a machine builds an approximate world based on the real-world data, then runs the simulation inside the virtual world for eons, ends up with the best possible, but still inferior action model (of course because the virtual world was not real), goes back to real world, adjusts the model, and repeats etc. It is even possible that our brains just do the same thing BTW. How many times do you run that scenario of a job interview in your head before you go there? How many times does it run in your subconscious virtually? How many times does it happen in dreams? And more profoundly, how often do those scenarios in our head are very inaccurate and simplified, and yet they still help us act in the real world nonetheless?
