The more busy you are, the more valuable your time... the more expensive context switching is. When you are known as the person with the answers, your day is at least partially structured around getting people to leave you tf alone so that you can actually concentrate on getting your own work done.
There's a really toxic expectation that people who are senior should stop what they are doing XX times per day to help other people figure out their issues. Usually there's zero consideration given to how much each one of these interruptions takes away from them. Resentment builds cumulatively.
Before LLMs, this conversation usually went like this:
"What should I do?"
"What do you think you should do?"
"X"
"Do X"
There's only so many times that can play out before you really want everyone to just fro.
Anyhow, you should try hard not to "hate and despise" LLMs. Life is too short to invent paranoid reasons not to use the best tools available. That's another instinct you learn as an experienced dev.
