> Is every company that sells software as their core business model going to go out of business?

Probably not, for a number of reasons:

* Some software suites are (probably still for a few years) too big to regenerate them through a coding LLM

* There's quite a lot of proprietary knowledge not just in the code itself, but in the requirements, industry knowledge etc. For example if you want to write a hospital management system, you need to know a lot about how hospital works, how they are billing their services in different legislatures, data protection rules etc.

* For some pieces of software (like computer-aided engineering), validation of the software is just as important as the software itself.

* Liability: suppose you build bridges, and you're on the hook if it fails too early. Do you really want to vibe-code your own software that validates the bridge's design? Will any insurance company cover that? Probably not in the near future...

* Currently, security and safety of LLM-generated code is still a pretty big concern. I guess this will get better as the LLM-Coding industry matures.
