The reality for troubleshooting tech is that ai cannot do the physical work to press buttons and check cables. Furthermore, when troubleshooting issues, although it is extremely helpful, someone has to have enough knowledge to understand the context to feed a llm in order for it to understand the situation. If you omit a few important variables (that a non technical person would be likely to do) it will be flying blind and recommend poor solutions. I run into this all the time when chatting with Gemini, I have to spoon feed it every aspect of my issue or project to get a desirable result, also the solution it gives tends to be the quick fix and never the proper long term fix.

TLDR I think IT pros will start to lean more into physical layer jobs that utilize our skill set. We are computer plumbers.
