I don't think that's gonna happen... unless I don't keep learning. Let me explain:

I started my career over a decade ago. I knew PHP and MySQL only. Then I moved onto other companies, learnt other stacks (frontend, node, postgres, cloud, go, python, datadog, ci/cd, docker, k8s, aws, etc.). Nowadays it's not hard for me to find a new job. But what would have happened if I stayed with PHP and MySQL and never learnt anything else? I would be jobless.

So, I'm not afraid of LLMs replacing me. I think they will open the door to more jobs in IT, actually.

I just need to keep learning (and AI has nothing to do with this).
