> Finance isn't "revolutionary" tech - there isn't much you can do that requires high risks and actually rewards you in the long run.
I don't think you read the article because it is based on a 700 page book about how it was revolutionary tech. It was just revolutionary finance tech. There was no ABCP before, there were no CDOs before, there were no central bank swaps before, there was no wholesale funding market, there were no offshore dollar banking market, etc.
It is hard to take seriously any arguments that the bankers were incompetent when you look at the sheer number of affected institutions -- you're left defending a claim that virtually every banker and most companies (look at the impacts on, say, Russian resource companies when they could no longer roll their dollar debt in wholesale funding markets in 2008) are incompetent. And that's always going to be difficult argument to make.
