I was a young kid during the dotcom bubble and in highschool during the '08 downturn so I wasn't really aware of the macroenomocic trends in the industry then, but now that I am older and deeply invested in the tech economy it's so obvious.
After getting into a couple very well funded startups, and seeing how the sausage is made, you realize that no one knows what they are doing. It's not that they're stupid, just that business is hard and the environment is always changing. Sure there might be some "master of the universe" types, but you can create a good business solving the most immediate and pressing problems.
These companies are either setting all-time profit and revenue numbers or just missing last year's all-time records. Wall Street wasn't happy that they just missed their growth targets, but keep in mind that all growth is compounded. So they have never been more profitable, and yet here we are.
In general I think the true leadership of many of these companies is overstated. Layoffs are way to appear to save money so they are doing just that. And the pandemic seem to have been growth in remote products, so they had to grow for that. Even if most of the new workforce might not have been needed.
Whataboutism is a word that has been abused badly a lot in the last year but it seems like it fits here.
