I've learned that training a model to search your (companies) unmaintainable, unorganized, and continuously growing documentation storage is a godsend.
For something like Salesforce development, you've got the answer spread across their old framework docs, their new framework docs, their config settings reference page, and a couple stack overflow questions.
Copilot / Bing search has legitimately been incredibly helpful at synthesizing answers from those and providing sources so that I can verify, do more research, and ask follow up questions.
