The problem isn't the computer models. It's the models that investment houses have been using generally. Telling a computer to do a workflow doesn't change the outcome. If it's a good workflow, it's a good workflow.

The problem is that many investment houses simply used bad quantitative data to evaluate their investments. Whether a computer generates that or a human calculates and writes it down doesn't change things.

I'm a big fan of trying new models with computers. Google does it all the time. However, when Google is doing it, the worst case is that the utility of your search results goes down.
