> Seems like such a waste of resources siccing a bunch of computers against each other in a zero sum game of stock arbitrage

Despite the useful service of price discovery (here are so many better ways) it is clear from the EMH that those computers are not doing arbitrage, they are front running trades.

Illegal. Criminal in USA (I think). But makes billions and billions for the already very rich. So that is why there is so much of it

Someone has to make the EMH hold.
