What I'm trying to get at is that age and stability are only loosely correlated with correctness. I'll give you credit for calling out the tautology, and I don't think there is a way around it. Any code that is written without rigor is going to be buggy. The age/stability thing is a category error.

The only thing I can conclude is that a more rigorous methodology for authoring code is more valuable than cleaning up after oneself later.

This absolutely matches my own feeling on the value of experience. Knowing what not to do is where practically all of my efficiency comes from, having learned that the hard way.
