No, I don't remember it like that. Do you have any serious sources from history showing that Segway hype is even remotely comparable to today's AI hype and the half a trillion a year the world is spending on it?

You don't. I love the argument ad absurdum more than most but you've taken it a teensy bit too far.

People genuinely did suggest that we were going to redesign our cities because of the Segway. The volume and duration of the hype were smaller (especially once people saw how ugly the thing was) but it was similarly breathless.

LLM are more useful than Segway, but it can still be overhyped because the hype is so much larger. So its comparable, as you say LLM is so much more hyped doesn't mean it can't be overhyped.
