Bubble of... 2023? This has been going on for a while. Since at least 5 years founders have known the way to get funding is to claim your product has "machine learning" or "artificial intelligence"
chatGPT is more then a bubble. It's a societal inflection point. The reaction to it is appropriate.
However as usual people will get too excited and the hype will outpace the actuality of the technology. There will be a slight "bubble" but this isn't anything like the "housing bubble".
Prior to chatGPT though, ai could be characterized as something along the lines of a housing bubble. I would say almost all lines of research in ai save llms are over hyped bubbles.
Not saying these lines of research are useless or inconsequential. Far from it. Ai outside of llms is amazing. But these Ais are definitely inside huge bubbles.
