I’ve been a technology nerd since before it was cool. In fact, when I went to college in the mid-1970s engineering students were treated more like George McFly than Mark Zuckerberg. It wasn’t the most glamorous major to talk about. Not much has changed today when I tell people I lead an advocacy organisation in support of high frequency trading (HFT), a technology that lowers trading costs for banks, asset managers and pretty much all investors. I find the work exciting, but I do run into my share of Biff Tannens.
