I actually think that would be a valuable exercise. Were they right about everything 20 years ago? Or just some things? When did they say AGI would arrive? Should that perhaps influence the way we interpret their assumption that AGI is right around the corner?

They were not right about everything and they - at least Yudkowsky - has not made specific predictions about "when AGI" will happen that I am aware of. But he did predict it is possible in our lifetimes, which I was very skeptical of. He did predict alignment would be hard - I was in the "why would we even hook it up to the internet?" crowd. He thought he should spend his time on that, and I wish he'd done more of that, or at least convinced others to do more of that.
