The faster market information thing provides no actual benefit to anyone, it'll just pollute the spectrum and maybe elevate the trading operations that were able to get licenses but ultimately it just puts everyone back where they are now because they're all just competing to make faster trades.
If FTL comms arrived tomorrow they'd all spend unimaginable sums of money and then all be immediately back at parity again. At the end of the day this proposal just means we lose, they gain nothing (though the ones proposing this probably expect to be able to exclude at least some of the competition by virtue of the very limited bandwidth) and tons of investor money is wasted on nothing.
We need to move to a quantized trading system where trades are all settled every minute or so instead of this war over microseconds all as part of a needless zero sum game.
