Because *shiny*.^† I've seen recently (ElReg, I *think*, but I can't spot it atm) a report of a survey that suggests people knowingly use low-grade news outlets because they prefer the flavour. I hereby dub this phenomenon "the MacDonalds Effect".

Even worse, from my trade:

Most devs don't trust AI-generated code, but fail to check it anyway

(Summary: checking is a higher-stress activity than coding, and said devs don't have time to do it properly. See also the Comments.)

† The old way to pronounce that was "GIGO: Garbage In, Gospel Out", because, dammit, said garbage has been filtered through a very expensive machine.
