Libraries and frameworks remove some boilerplate but there's still tons of it. It's rare a library exposes a single doTheThingINeed() function that runs a business. Everyone needs boring but domain specific code.

A PoC has never really been a problem that needed solving. It's going from that to a product that's actually fit for purpose. AWS will happily drain your bank account because you're throwing tons of resources at a poor implementation. Hackers will also happily exploit trivial security vulnerabilities a vibe coder had no ability to identify let alone fix.

This is not the first time the industry has been down this road. They're not in themselves bad tools but their hype engenders a lot of overconfidence in non-technical users.
