Their "is hft good or is it bad? it's opinion! <but look at all these scary things they are "responsible" for>" bit is really disappointing. I see it in articles all over the place and it's really lazy research and reporting. Isn't this article about the tech? Why are we suddenly having an extremely off-the-cuff discussion on whether HFT is "good or bad"?
Also, I have trouble reading the tone of the article. I hope the "making trades in the past" and "until someone manages to break the laws of physics" are completely in jest. I know it's probably a joke, but it's a poor enough excuse for one that it just leaves me wondering if they might actually be somewhat serious.
