When people say 'AI isn't a bubble because the technology isn't going away', it just shows they don't know what a bubble is.
The internet didn't go away. Railways didn't go away. Tulips didn't go away.
An asset can be overvalued, even if its useful.
I really admire your ability to carry on trying to educate people on issues like this. Personally I find it difficult not to get thoroughly depressed by that level of ignorance.
Do people say ‘AI can’t be a bubble because the tech isn’t going anywhere’ (which I agree is false) or do they say ‘there’s an AI bubble but when it bursts that probably won’t mean AI goes away’ (which is probably true)?
