Not that I ever had confidence in his technical knowledge, but it went to zero when he confidently asserted that there was no possible way a single server could handle the massive traffic some NextJS app he had made was serving. He then posted the bill - which was about $5K IIRC - and I was able to determine from the billed runtime and memory that a modestly-spec’d RPi could in fact handle it.

He's about as knowledgeable as the junior you hired last week, except that he speaks from a position of authority and gets retweeted by the entire JS slop sphere. He's LinkedIn slop for Gen Z.
