I was in Tech for the .Net Crash and in Finance (in Lehman Brothers, no less, so front row) for the 2008 Crash.
To me what's going on now stinks of both, because there's not just one bubble but several, the biggest of which being the Tech Bubble around AI and the Realestate bubble responsible for the several fold higher house prices (in terms of house price to income ratio) than then historical average.
I expect that when one blows it will most likely unballance the broader Economy enough to cause the rest to blow.
