I like Michael but do not like Fareed, so i did not watch., but regarding the topic. Technology is not replacing the wall street... Wall Street always was and will be about skimming off the market, and how you do it: by hand or with computer not as important. What's important is that Wall Street's edge compare to the public is and will be in its place on the market. So they make money off the market not on the market. As long as guys on wall street will remember that and will utilize this edge (and not imagining, as they have once in a while with the catastrophic results, that they know how to make money on the market) they will be alright.
