When the dominant voices begin to claim, "This time it's different!!" that's usually a sign we're nearing the end.
Look this up. During the dot-com bubble, the popular notion emerged that the business cycle might have ended. "The end of the business cycle!!" Many media outlets pushed the narrative that humanity would experience endless growth thanks to technological advancements.
During the housing bubble, towards the end, multiple media outlets suddenly started repeating the idea that housing prices, in real terms, have never fallen.
When I heard that farcical argument gain steam, I got out of housing immediately—before the bubble burst.
So, for me, that AI-bubble skepticism is still the dominant opinion suggests that this bubble is far from over.
I think we're closer to the Netscape IPO than we are to the .com crash.
Maybe we're at the halfway point. Just one person's opinion.
