Where's the logic in this? - I don't understand thing ABC, therefore I won't form an opinion on it (true fact, by his own admission... conservative and reasonable). - Thing XYZ is generally acknowledged to be more complex and harder to understand than ABC (debatable, but I'd love to see someone show me how crypto is easier to understand than Google/Facebook/Amazon/Uber/etc.). - Even though I don't understand ABC and won't form an opinion on it, I will form an opinion on XYZ which I understand even less (... wut? Why would anyone put stock in this statement, given the prior two statements?).
