Staff+ work is not that much (exclusively) coding anymore, but identifying correct big things to work on and keeping focus on it, making Bob and Steve from different teams talk to each other instead of building the same stuff twice, making opinionated decisions on things, blocking harmful initiatives, finding elephant in the room and saying things out loud that no one wants to say etc.

It's not really the work that LLMs currently do. I mean sure, maybe if you plug an LLM to read all emails and slacks and zoom transcripts of the entire company, it could do it at some point in the future. But would it have the same amount of influence compared to an industry & company veteran who has the company specific knowledge and experience that is nowhere written down?
