He's pretty clearly saying he beilieves the technology capable of such a feat, at least in theory, which is far more than many would deign to admit even a year ago, nevermind 7. He had the right idea/model of LLM capabilities, which is more than you could say for a lot of people, even in this very thread.
If that’s your standard for what counts as prediction, Asimov beat him to it by seventy-ish years.
EDIT:
> Scott made comments on a specific emerging technology
He was speculating on what would happen if one gave GPT-2 “near-infinite training data and compute.” It’s a thought experiment, not a prediction. Near-infinite amounts of anything is a fantasy.
I acknowledge that he has predicted some things in a falsifiable way and turned out correct, but this isn’t one of them. You’re reading hindsight into the text.
