I think that this is your best path forward. Go simulate some rigid-body physics. Simulate genetics with genetic algorithms. Simulate chemistry with Petri nets. Simulate quantum computing. Simulate randomness with random-number generators. You'll learn a lot about the limitations that arise at each step as we idealize the real world into equations that are simple enough to compute. Fundamentally, you're proposing that Boltzmann brains are plausible, and the standard physics retort (quoting Carroll 2017, Why Boltzmann brains are bad) is that they "are cognitively unstable: they cannot simultaneously be true and justifiably believed."

A lesser path would be to keep going with consciousness and neuroscience. In that case, go read Hofstadter 2007, 'I' is a strange loop to understand what it could possibly mean for a pattern to be substrate-independent.

If they’re complex enough, and executed sufficiently quickly that I can converse with it in my lifetime, let me be the judge of whether I think it’s intelligent.

No, you're likely to suffer the ELIZA Effect. Previously, on Awful, I've explained what's going on in terms of memes. If you want to read a sci-fi story instead, I'd recommend Watts' Blindsight. You are overrating the phenomenon of intelligence.

I'm clearly failing to communicate my thoughts, and doing it in the wrong forum, but I appreciate the links, I'm excited to learn new things from them.
