People in the comments wish to provide assistance and share their experience, clearly missing the fact that the person asking didn't even bother to do a simple search first.
I use llms everyday for coding assistance the same way I used search engines in the past, and to that extent I do not see an issue. Why would you avoid that out of principle?
I don't have advice, all I wanted to say is: As a software developer who will almost certainly never retire, with little savings and living in a craphole of a country somewhere far from the USA, I wish I could be in your position.
If you don't have other health issues and/or disabilities, then what's left is to either change your job, or the people you are surrounded by.
