> imagine if we continued to grow and didn't have all of those extra people
This is the problem with FAANG, to a very large extent with all VC-funded companies, and to some extent with capitalism in general. Everyone looks at total dollar value, not at efficiency (loosely revenue per employee) and certainly not at anything hard to measure in dollars (e.g. quality of life). The only way to keep driving that number up is to grow, not to improve. Growth is mandatory, necessary even, and ultimately becomes like that other thing that keeps trying to grow without bound: cancer. Innovation is an uncertain route to growth over the long term. The sure routes are monopolization, regulatory capture, rent seeking (especially in the form that Cory Doctorow has called "enshittification"), and so on. So guess which one CEOs - whose pay is tied to that growth and not to more human-oriented metrics - go for. Every time.
