It's an interesting dream team. But AFAICT this is only a proposal. Did the proposed series of studies take place? If so what was the outcome?

I think the result was this: https://en.wikipedia.org/wiki/Dartmouth_workshop

I wonder if they were the dream team back then or just promising young researchers.

I think the interesting take away is that they (seem to have) expected to solve the major problems of AI (language, common sense etc) over a summer with a small stipend.
