Because Scott somehow manages to forward-activate the neurons of many people who read him. I'd say he's in the "top 5" of topics that show up most frequently (gwern has fallen off signficantly). He's a clinical psychologist, but he's got a collection of weights driving his writing that manage to make a subset of tech people feel something.

Like Malcolm Gladwell but not an NYT bestseller, so cooler, or something. Also, minor point, he is a psychiatrist (MD).

I stopped reading when I got to the part where it became clear that Scott Alexander was the "Silicon Valley's Sharpest Minds" of the article title. Why not ask Hulk Hogan or Barbara Walters to evaluate Google's AGI?

Because neither of them are recommended by the CEO of OpenAI, and followed by the head of MIRI, Paul G, and Vitalik for good reason?
