This is exactly correct. We have seen “market maturity” which basically means “tech companies are now run on modern management theory” and that theory, frankly, is wrong. Open doors, frank discussions, flat hierarchy, hacking culture, planning at the edge, and personal relationships all took a dive. Performance plans, recruiters, mid-level managers, central planning and product management overuse exploded. Somewhere around 2014-2017 working in a tech company started to be indistinguishable from working in any other Enterprise. Now a lot of that seems to be the result of all the pioneers leaving the industry and the settlers arriving. There was a point around 2012-13 where Ivy League grads stopped going to McKinsey and started going to the valley, and they brought all their management theory with them.
