AFAIK its theorized much of the GDP growth of the US, as well as the stock market growth of important index funds, is mostly as a result of select tech companies surfing the AI hype.

In that case, a prolonged recession may occur (that would've occurred anyway), and the effect will be felt throughout the economy.

But, again, that's just a general recession being triggered by the AI bubble bursting, i.e. AI no longer propping up the economy, so that's not a bad thing. What the results of that are in terms of severity or impact I wouldn't know, I don't think anyone knows.
