In this respect he strongly reminds me of Mencius Moldbug. However, also like Mencius, he seems to have a very political/social focus which fuels my suspicion that many of his top down "grand theories of how reality works" are false.

Oh yes, this is the aptest comparison on the page (a comparison to Robin Hanson would not be amiss either), except I get the feeling that Moldbug is more of a single big idea thinker than Rao (if you used Tetlock's dichotomy, Moldbug is a very happy curled-up hedgehog, and Rao would be the fox, possibly a fox on Adderall).

Both are provocative thinkers who probably are only occasionally truly right. But that's better than most writers, who are never right or provocative.
