Nothing is truly perfect. Maybe in 5-10 years we'll have massive 3D printers that can build you any house without needing a big construction crew. I doubt but if you asked me 5 years ago about AI being capable of replacing me, I'd have laughed in your face... Alas, here we are.
Not replacing, augmenting. Try to find ways to use the new tools to become more productive than other engineers. Help evolve integration and deployment frameworks to handle the snippets from LLMs in the context of larger projects with a minimum of glue.
I wouldn't be surprised to see some old ideas come back to life like encapsulation concepts from enterprise software development. But this time we let LLMs deal with the boilerplate code needed to use and connect them.
