Everyone’s talking about encyclopedias but they weren’t always that useful either. They can only fit so much information in those books so some topics would only get like 3 sentences dedicated to them. So yeah, if you were writing a research paper for school you’d spend lots of time at the library trying to find books that had another smidge of information you needed.
If you were lucky, you’d find a really good book that was very relevant to your topic and lean heavily on that. Otherwise, you’d wind up with like a few sentences each from a dozen books that you have to tie together somehow. Wasn’t fun.
If we’re in a simulation, it’s probably a massive universe-spanning one. We’re just a blip, both within the scale of the space of the universe and within the history of time of the universe. In that case, we’re not important enough for a simulation creator to even care to adjust our capabilities at all. They’re not watching us. We’re not the point of the simulation.
