Not FANG, but I work at a company that operates some infrastructure at scale. What I've seen is after we've rotated through a number of different tools, in different pilot groups, eventually converging on tool X (a custom, internal wrapper around opencode).

Now every "working session" like meeting, at the team or dept level, has been around how to use tool X. Tricks using tool X. Problems using tool X. I can't help feeling if we had spent the same amount of time building up core knowledge/contempencies around say, design patterns, networking, specs, we'd be in a better place for building.

Instead we are going to have a few thousand people who know a tool really well.
