You read on here: it is just tales of giga, 10x programmers...I only work at companies with sufficient technological prowess, 7 figures, I expect my workplace to be staffed with those of similar intelligence to myself, Ivy League PHds only, send me full resumes of everyone who will be on my team, I only deal with problems that are world-changing...on and on.
You read financial statements: inept management, no controls, massive staff expenses, development budget is usually totally out of whack with revenue, growth in staff faster than revenue, struggle to develop new features (despite a relatively simple product), over-engineered, bloated maintenance...on and on.
Financial statements don't lie (the consistency between these two stories is: most engineers are massively overpaid, they aren't good at doing useful things, many tech companies have monopoly products, they then hire lots of engineers who do nothing but bloviate about how influential they are).
In the case of TWTR, comically mismanaged company. I don't know where the bloat is but Dorsey isn't someone who should be running a listed company (and has crashed and burned several times at Twitter alone). The guy who he appointed was an obvious stooge who was clearly not up to it. If nothing else, hopefully Musk will put them back on an even keel (I don't Musk is a good exec either, but this job is far simpler than Tesla so hopefully he will bring them back to an even keel).
