I think part of intelligence is the ability to recognize patterns that can be abstracted and generalized, and memorizing data is just one means of making the data available to your brain for pattern recognition. Like, if you come up with a possible theory, the quickest way to test it is to see if anything you already know would invalidate it; so the more you know, the more quickly you can sift through possible theories.
So, yeah—education reminds you that you might be wrong, while memorizing things gives you a tool to prove yourself wrong.
No, but AIs will be able to generate a statistically accurate simulacrum of a set of people like us.
