All of these tech companies have fallen into the Wall Street trap and it will be their ultimate undoing. Meta probably more than most.
I feel like a broken record but Google cracked this particular nut in the 2000s by creating an environment where people could flourish who would otherwise suffer in Corporate America. Google studied this and found in the 2010s that psychological safety was the number one factor in team success [1].
Corporate America typically has what's called an "up or out" mentality. Jack Welch dogmatic thinking rules here. Fire the bottom 5% every year and if you don't get promoted within a certain period, get rid of you because you've reached your potential. This is what created things like stack ranking (which is nothing more than a popularity contest) and smoothing of performance ratings. The last one is toxic because a certain percentage of ratings have to be subpar (ie below "Meets Expectations"). All of this destroys collaboration and creates an environment where those who are more political and more likable rise to the top.
And guess what? Your autistic engineers who otherwise flourished in early Google can't function effectively in such an environment. And these are the people who otherwise become subject-matter experts in storage systems, networking and other niche topics.
At some point innovation ends and the only way to satisfy the insatiable appetite for increasing profits is to raise prices and/or cut costs. So all these companies have engaged in the suppression of wages despite being wildly profitable on a per-employee basis.
As for Zuckerberg in particular, he clearly has no idea where to go with Meta and the AI division is a disaster. The posterchild for bad decision-making and leadership was the Metaverse because $70B+ was spent on an idea with no product-market fit. There were other less expensive boondoggles (eg Libra).
So Zuck hired like crazy in the pandemic because that's what everyone else did and has now engaged in massive layoffs because, well, that's what everyone else is doing and he has no idea what to do with those people. Notice how it's leadership errors that are massively disruptive to people's lives but they suffer none of the consequences when they're responsible? Yeah, me too.
