Yes. The other 3 groups were not AI researchers. And the TOP100 group had a response rate of 29%, which adds self-selection to the process. People who are interested in AI risk et al. are more likely to respond to such a survey, adding bias. Andrew Ng or Yann LeCun or anyone actually working in AI would have refused (and probably did refuse) the invitation. Also, this TOP100 group of people are also more likely to be GOFAI folks who pretty much have no idea about the current data-driven deep learning-based AI.

Even Stuart Russel, the only CS guy in the AI risk camp, doesn't actually believe that AGI is anywhere near. But he works on it simply because he thinks we can do solve some of the problems like learning from demonstrations instead of (possibly faulty) rewards. That's actually a core AI research topic, not a AI ethics/values/blahblah topic. Oh, and also because this allows him to have a differentiated research program, and thus directs any funding on this niche to him.

Seems pretty clear neither of us will convince the other in this venue, so I'm going to leave it here. Thanks for the discussion :)
