The code created by generative models will still need to be verified by a dev. The industry will change. I don't even question that anymore. There was a similar wave when we started to Google everything and were able to find a ton of useful content on stackoverflow. Some devs adapted, some became obsolete. I think developers will be able to upskill faster and be more productive. In turn, the projects will just get more ambitious.

To your question, I would not worry.
