In fact, it's more encouragement to continue. A lot of issues we face as programmers are a result of poor, inaccurate, or non-existent documentation, and despite their many faults and hallucinations LLMs are providing something that Google and Stack Overflow have stopped being good at.
The idea that AI will replace your job, so it's not worth establishing a career in the field, is total FUD.
By the "past year's worth of development" I assume you mean the layoffs? Have you been in the industry (or any industry) long? If so, you would have seen many layoffs and bulk-hiring frenzies over the years... it doesn't mean anything about the industry as a whole and it's certainly a foolish thing to change career asperations over.
Specifically regarding the LLM - anyone actually believing these models will replace developers and software engineers, truly, deeply does not understand software development at even the most basic fundamental levels. Ignore these people - they are the snake oil salesmen of our modern times.
