Yeah, I've never personally worked at any of those places, but collaborated on a few open source projects with Googlers and Xooglers and the slow grinding wheels of their "processes" that wear people down over time were very apparent. Nevertheless, it has been a breeding ground for many interesting technologies, even if it often suffocates them over the long term.
Wouldn't be possible nowadays to LLM your way out of this?
Really no idea, just asking.
Honestly, the whole thing felt LLM to start with, tons of people lacking context and throwing words and summaries around.
Couldn't have said it any better myself having worked at AWS for close to 8y. I was there during their peak growth years and remember very well how some of these processes that were once not as maddening, devolved.
