In my opinion, he asks the right questions and lets the guests speak, which is something that can't be said about the rest of tech podcasts.
For example, at some point I grew very tired of the superficiality of the questions that Lex Friedman asks his very technical guests. He seems to be more interested into taking the conversation into a philosophy freshman's essay about technology instead of talking about technology itself.
Hearing the Dwarkesh podcast was a breath of fresh air in that regard.
