Which AI bubble? The stock bubble one or the imagined "one day all the LLMs are going to disappear from the face of the Earth" one?
So the predictive autocomplete will survive those too.
And the dot com bubble collapse of Nortel and Worldcom shows that even well-established companies with significant non-bubble investments are vulnerable if the companies make poor economic decisions (in both of those cases, the collapse was driven by excessively aggressive acquisitions).
Likewise, LLM's won't disappear completely with a stock market crash. But the weaker players might.
