Why do you think it would be a prolonged recession? Dot com bust, for example, was just two quarters of GDP decline, followed by solid growth. 2007 was much worse, because it was a crisis of financial institutions. AI bubble may be bigger than dot com, but feels more like it in that is a narrow section of the economy. Even more narrow than dot com.
Well I think nobody knows this stuff, so don't take my word for it. I think prolonged makes sense because AI is holding off a depression, but that depression does not have a singular obvious cause. I think there's a bunch of reasons to be pessimistic about the global economy, including of course (geo)political, (trade)wars, extremism, stagnating production, etc. Contrary to the dotcom bubble, current AI might not actually be a useful-but-overvalued tech. It may just not be that useful at all. In that case, a rally like dotcom is out.
