Dude, if you're referencing information theory you clearly don't understand how to create tech. Obviously they're not trying to simulate the universe accurately lol. Simulating the real world for specific use-cases to solve computer vision for practical applications is super interesting. If they have customers, makes sense.

That's assuming human minds and computers won't exponentially increase their processing capabilities. Moore's law disproves the later and I hope Neuralink or some other crazy tech company will disprove the former. That's pretty much the hope of all transhumanists.
