If writing code was the only value your employer ever saw in you, it's for the best that you're forced to find a better job now. You would have eventually hit this point in your career anyway regardless of "AI".

The broader corporate world has never wanted code monkeys. They want "boring" reliability and pay a reasonable wage for it. On the other hand, they also won't tolerate contrarians who can't deliver, so maybe some of the fear from people posting this sort of thing really is justified.
