Quality is what we call the difference between what succeeds and what we wish succeeded. It's a measure of how closely the opinion of the person saying "quality" aligns with what is actually rewarded by the fitness function that objectively exists. The only thing you've learned when you hear "quality" is what the speaker thinks is good, not anything about the subject.

Quality does not exist until a (person, preference, subject) pairing happens. It's not real. It's literally not a thing. It's just a name for mixing up your is and ought.

When someone saying "quality" can point to the specific property that makes the subject quality, they're almost always pointing to what is, from the perspective of the fitness function, inefficiency, a waste of energy and effort, more spent than the system rewards.

Anyone who spends a lot of effort building skills to get particular results is going to believe those results are important, at least a necessary part of success, if not the whole definition. When people who did not put in the effort keep succeeding without those results, "quality" becomes the cope. It's shoddy work. They did it wrong. They cheated somehow.

And yet they succeeded.

Because "quality" is what a person says when is and ought don't match, a fact about the speaker, not the subject.
