AI-assisted coding is great, but vibe coding IMO is only good for disposable prototypes.

You're not going to vibe-code a financial app that needs to be maintained indefinitely.

You're also not going to mess with legacy systems.

I think that AI has definitely replaced _some_ engineers, but I don't think your use case is relevant. Your non-engineering friends have created their pet project because they now can, but it's not as if they were going to hire anyone to do it, right? They haven't up until now.
