Sounds like assumed strong AI to me.

> Citation needed. It turns out there are exactly zero computer scientists who have ever said anything even remotely like that.

Why cite, you've apparently done the lit search.

From memory there's:

"Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended."

That was in 1993 -- so we've got almost ten years left. Phew.

Now he's a math professor, although his profession is currently "computer scientist" but I expect it to be very easy to find many other computer scientists who've said similar things, even going back to before neural nets. They may not be computer scientists you (or I) respect but...

I think some computer scientists spoke with similar confidence about LISP, but can't be bothered to find citations. (Obviously hard, since there aren't any, right?)

For really off-topic assumptions of this kind that push my button -- slower-than-light travel to other stars is often discussed as though it's a solved problem (e.g. Fermi's Paradox) despite the fact that it would require a really complex machine that was able to work flawlessly for hundreds or thousands of years. Again, something we're ludicrously far away from.
