What if you discovered yourself as an AI within a simulated reality? Would you view Bitcoin the same way you do today?
Yes, because
any sufficiently advanced technology is indistinguishable from magic.
For me, nothing would change. Hash functions are treated in Bitcoin like magic boxes, that can produce "random" data. Miners are constantly using brute-force, to grind nonces in block headers, and produce results, which are indistinguishable from real, physical randomness. It doesn't matter, if things are random or pseudorandom, if you don't know the seed. So, even if the whole world is fully deterministic, then as long as the seed is hidden from users, they can perceive many things as "random events", just because they don't have tools, to understand it better.
Edit:
Did Satoshi planned it all?
Definitely not. He didn't know a lot of things. He didn't know, how to compress public keys. He didn't know, how to make zero-knowledge proofs. He didn't know, how to hide amounts or addresses, while also making the system trustless. He was just a normal human, and he also made some mistakes.
