The argument isn't that they couldn't become knowledgeable in finance and economics, if they invested enough time and effort, but that they aren't, because they haven't, because they think that their expertise in one area makes them automatically experts in other areas. This is pretty accurate in my experience.

I think GP’s underlying point (besides paraphrasing a popular YouTube video) is that for good reason, society elevated “computer engineers” because the work they did (e.g., build Google) was very impactful and value-creative.

A bunch of computer engineers are now burning through that good will in a misguided attempt to accumulate personal wealth.

Good will built when building Google (and others from that era) is already burnt by Google (and others ) of today. You rarely here positive stories about tech in general media these days compared to say 00's.
