Since I develop and run my own automated trading systems, and I am members of a few exchanges, I guess I am biased.
Yes, in a way, today's electronic market is all about better models (better quants), faster speed to the market, etc, and people have complained that firms that can afford to pour millions into their system and tech infrastructure has the advantage.
But the floor trading at times is worse, it is an old boys club, where I will feed order to you, not because you have a better price, it is because you are my friend / uncle / father-in-law / drinking / coke buddy, it doesn't matter the client would get nicked a ticker here and there, it is all about keeping it in the club (family). Honestly, even as an exchange member, I haven't been to the floor for over 8 months now (I am not even in the same city), and I won't miss it a bit.
Yeah, the floor locals that can't adjust are at the end of their careers (NYSE members, welcome to new world), and I know a few that have sold their seats and opened bars, even one that is now driving an cab, but that's evolution.
