Note that this is business and economy academia, not real science. It's usually scientism at its peak: mathy explanations that use complex equations to describe poorly modeled phenomena and arrive at the previously decided on conclusion that the authors wanted to show. There's few other domains quite as smoke-and-mirrors as this (social sciences probably being the other, though they tend to at least steer clear of the complex math).
I have been following the market. Some of the most popular tech stocks have dropped back to pre-covid levels. During covid my inbox was blowing up from Meta, Amazon, Microsoft recruiters. This behavior clearly correlates with the stock evaluation. Literally everyone I know in tech was able to make good moves or get raises. Uncool companies had a hard time competing with SV giants.
I can cite the hiring frenzy, the stock evaluation, HUNDREDS of articles that disagree with his "SIMPLE" answer.
