"Vibe coding" implies minimal to no human involvement. It doesn't matter how good of an engineer the person who typed the prompt was, they were not involved in writing or reviewing the code, so the end result will not reflect their skill. The whole point of vibe coding is making software engineers irrelevant.

People like to go on about how "good engineers review their AI code" but that's just not what's happening in reality. Not only is reviewing large amounts of AI generated code unpleasant and mentally taxing, it also negates most of the perceived productivity boost, so people are simply not doing it.

> Proper testing

There is no formal testing that would be expected to catch an issue like this. It can barely be classified as a bug, the logging is working as intended, just with negative side effects that weren't accounted for.

The only real way to proactively prevent an issue like this is for a human programmer to stop and think about this code as they're writing it and go "hmm, we're logging large amounts of data to disk at a fast pace here, this may be a bad idea". Without human involvement, this is just going to keep happening. All vibe coded software is bloated and unstable, I have yet to see a single counter-example.
