Can you explain why computers cannot simulate Turing machines and how that relates to the quote? My reading is that the quote says "to reach agi, it's not enough to learn a sequence of steps in text, we will want the agi to be able to crystalize (compile) that sequence of steps into a program run without abstractions on its native system." Presumably because it's too slow to run it on top of an LLM. Stretching further. I think humans do crystalize learning into things that look hardcoded, like muscle memory or reflexes, rather than talking themselves through everything.
