No, never did it for a living (did consult for some over the years) and this sort of ad hominem nonsense pointed towards people who know what they're talking about is why we can't have nice things.
It wasn't ad hominem, it was largely in jest as most of the people I've encountered who don't like Michael Lewis are HFTs who didn't like Flash Boys. If you are worried about substantial discussion here, perhaps you could start by detailing why you disagree with Michael Lewis, rather than dismiss him outright with generic, detail-devoid dismissals that he doesn't know anything, as opposed to yourself who does "know what you're talking about".
Again, a non-substantive response and deflection. I don't care what credentials pop up when I google your name. You still have provided no actual critiques of anything Michael Lewis has claimed or stated, and instead you continue to make the same "appeal to authority" fallacy (while simultaneously failing to prove why you have any more authority than Lewis).
If you would like explain why Lewis is wrong, I'm all ears. Otherwise take the meaningless criticisms elsewhere.
