Instead of reaching for this horribly irritating snark (I'm sure GP understands market making enough to understand why HFT exists), why not be charitable and consider the opportunity cost of the smartest people spending their mental energy to create a slightly more efficient market? Is this really a responsible use of this resource?

Consider a similar irritation when seeing those with a superficial grasp of a complex topic oversimplify and make unwarranted conclusions.

And it's precisely the GPs unwavering certainty that HFTs are net negative that accurately informs they do not understand the full implications of what HFTs offer.

Because when you're aware of the full picture, it is not at all obvious society will be better off without it.
