One thing about vibe coding is that unless you are an expert in what you have vibe coded, you have no idea if it actually works properly, and it probably doesn't.

Worse yet, if you're not an expert(with autodidacts potentially qualifying), your ideas won't be original anyway.

You'll be inventing a lot of novel cicular apparatus with a pivot and circumferencrial rubber absorbers for transportation and it'll take people serious efforts to convince you it's just a wheel.

In most domains, working on a project for a few years will make you an expert.

Working? Maybe. Prompting? Unlikely.

And in some other domains it takes a few decades to get to the top technically, not just a few years.
