the people ordering it used are mostly very stupid

We met with my mom's tax preparer a couple of months ago. He wasn't able to get anybody's taxes done on time because his super-expensive tax prep software crashed and burned on him. I told him it was possible (if not probable) that the software had become vibe-coded and his problem was AI. He surprised me by going into raptures of joy over how great AI was. He then told me that he had invested tens of thousands of dollars in some dude who was developing a "reactionless space drive", and that this guy had solved all the problems he was having with it by using ChatGPT. I asked him if the dude had a working prototype and he said no, but it was sure to work now that ChatGPT had fixed it.

I considered explaining to him how LLMs work and what "confidently wrong" meant, but I thought better of it. Now I have to find a new tax preparer for next year.
