I have seldom seen predictions about technology come to fruition at the predicted date. If they come at all (they usually don't), it's usually much later. Sure, some naysayers might have said "we will never solve chess/go/etc." but I think they were overall fewer than the people who thought it was right around the corner (and it was more of a philosophical argument than a scientific one). Totally unpredicted advances coming out of the blue, yeah, that happens often. But as far as AGI goes, it's been predicted pretty much every year since the 70s. Being too conservative about extrapolation doesn't seem to be our problem. If anything, I think we're overeager.
