In your hypothetical, I think it would be more apt to ask if it could do so strictly using training data pre 2005. Seems more analogous to "could it take over the world today".

No, training data has nothing to do with this. My point was that "you can't take over the world with tokens" is not a valid counterpoint in the doomer's position. Because their view is that singularity can happen. And when that happens things become murky. And 20 years of progress can go in 2 months "real time". Or two weeks. You get the point.

(I don't share their view, btw. I was just trying to say that the argument of tokens can't affect the real world is not a good one, if you steelman their maximalist position)
