However, pouring unspeakable amounts of money, watts and person-hours into completely unnecessary and wasteful infrastructure just because emergent properties of a system mean that billion dollar companies and their owners can make a lot of money by being a picosecond faster than each other in an eternal battle is of extremely questionable utility.
What exactly do we as a society get in exchange?
Arguing about HFT feels like you're questioning people about why they're spending billions on excavating single, individual sand grains and the defense you get is "well, sand is an incredibly important building material. It is used in concrete, and we wouldn't have modern society without it". Sure that's true, but why is it that nobody can tell me how what you're doing is actually necessary for that.
Does that require HFT, or just T?
That's the theory, anyways.
No.
Market event A is seen to correlate strongly with market event B. The correlation is so obvious that multiple participants compete to make the B trade first in reaction to A. It's part of having a healthy market, electronic or otherwise.
Besides the definition of what constitutes a "white supremacist" has been getting more ambiguous by the minute over the past few years. Nowadays it pretty much just means "anyone who doesn't like illegal immigration" or "anyone I don't like, but I'm too lazy to articulate why".
Your post is similar to if I proposed a hypothetical about addition using apples, and you posted a screed about how apples are overused in American cuisine and their nutritional value is suspect, especially relative to oranges and pears.
Just the other week I saw the news that until recently we had 300 (!) Saudi nationals training to fly planes right here in the US. Software won't help us with stupidity/sabotage of this magnitude.

I'm not in favor of surveillance panopticons either, for what it's worth.
Still, that's very few events, which supports my point. It's basically a more potent "think of the children" trojan horse that routinely gives the government even more power (and potential for abuse) through harebrained and ineffectual laws. See e.g. the current FISA abuse scandal where the FBI _falsified the supporting documentation, and knowingly supplied fake documentation to the court_ to spy on a presidential campaign. Had it been you or me they spied on, nobody would even know.
Again, I agree with you that domestic extremism (be it white supremacist, Muslim, or Black Hebrew Israelites) should be countered through ordinary policing, rather than building the Stasi's wet dream.

That’s it off the top of my head. I know that sometimes secondary effects can happen (e.g. an oppressive government may use a database, and I might work on that database) but that’s not me directly helping them.
Something like this, feel free to add others everyone!
