The hype is just lagging indicator of the underlying factors, like investments. It would be better if the AI fewer would inflate to sustainable level gradually, but it's not likely to happen. Even if AI/ML field is in good shape for long term, its still likely that investors overshoot in short term. Overshooting leads to period of underinvestment that hurts.

I don't think anything going on on HN is evidence of any pending "AI Winter". Actually, my personal suspicion is that there aren't going to be any more "AI Winters" at all, at least none of the severity seen in the past. Maybe there will be an "AI Fall" at some point. But existing AI/ML techniques are already creating so much real world value that people aren't going to start dropping it like a hot potato like they did with Expert Systems or whatever.
