I’ve heard my own CEO try explain something technical and it’s clear they don’t really understand it (and why should they? That’s why they hired experts).

In this article Bill says “most of the Covid tests are garbage”. That seems like a technical statement that should come from someone who is an expert in testing.

If the question was “what do you think the most promising Covid treatments are?” that’s a good question for Bill, assuming he’s involved in the funding decisions (maybe he’s not?).
