> I think you are not going far enough though: All code is legacy code. So vibe coding's ability to make writing more code faster isn't special because it's code nobody understands: Your hand-rolled code is also bad.

This is "but humans also", which I believe should be a recognised fallacy at this point.

Not all code is legacy code, for one thing; some is small enough that it is absolutely live in the minds of developers.

The best practical definition of legacy code is that it is voluminous, entrenched and owned by nobody currently in the organisation. Vibe code typically meets two of those requirements the moment it is produced.
