The AI "bubble" won't burst just like the "internet bubble" didn't burst. the dotcom bubble was a result of investors jumping on the hype train all at once and then getting off of it all at once. Yes, investors will eventually find another hype train to jump on, but unlike 2000, we have tons of more retail investors and AI is also not a brand new tech sector, it's built upon the existing well established and "too big…
OpenAI has ~4B of revenue already, and they aren't even monetizing aggressively. Facebook has an infinite money glitch, and can afford to put billions in the ground in pursuit of moonshots and Zuck's own vanity projects. Google is Google, and xAI is Elon Musk. The most vulnerable frontier lab is probably Anthropic, and Anthropic is still backed by Amazon and, counterintuitively, also Google.
At the same time: there is a glut of questionable AI startups, extreme failure rate is likely - but they aren't the bulk of the market, not by a long shot. The bulk of the "AI money" is concentrated at either the frontier labs themselves, or companies providing equipment and services to them.
The only way I see for the "bubble to pop" is for multiple frontier labs to get fucked at the same time, and I just don't see that happening as it is.
