I don't think that Gromov's views and Eliezer's views are necessarily incompatible.

My reading of Gromov's quotation is that he does not have his eyes on a technological intelligence explosion and that the existential risk that he's presently most concerned about is natural resource shortage.

This is in contrast with Eliezer who does have his eyes on a technological singularity and does not presently seem to be concerned about natural resource shortage.

I would be very interested in seeing Gromov study the evidence for a near-term intelligence explosion and seeing how this affects his views.

I may eventually approach him personally about this matter (although I hesitate to do so as I think that it's important that whoever approach him on this point make a good first impression and I'm not sure that I'm in a good position to do so at the moment).
