If it's stupid, but it works, it isn't stupid. Gas town transcends stupid. It is an abstract garbage generator. Call it art, call it an experiment, but you cannot call it a solution to a problem by any definition of the word.
It is simply because Mr. Yegge is seeking attention. As he always did.
"If it's stupid, but it works, it isn't stupid" is a maxim that only applies to luxury use cases where the results fundamentally don't matter.
As soon as the results actually matter, the maxim becomes "if it works, but it's stupid, it doesn't work".
