"At 9:43 EDT, the devs decided collectively to do a "rollback" to the previous release. This was the worst possible mistake,"
No, the WORST POSSIBLE MISTAKE was doing a major roll out, then NO ONE STICKING AROUND TO WATCH WHAT HAPPENED! Seriously, who does this?? It's like lighting the fuse on your firework show, then having an all hands staff meeting in a sound proofed trailer with blackout curtains.
Why does hft even exist? Does it have any value?
Short answer:
It gave us compiler explorer, now that it has served its purpose we should stop doing it.
Long answer:
Hft can exist because most stock markets react to requests as fast as possible and have no noticable fees for certain use cases. This means algorithms that do simple trades like if goggle goes up, buy other tech companies or buy any stock that goes up in europe on the NY market can make small profits if they are faster than everyone else.
There is one exchange that imposes a delay on every request, effectively inhibiting hft, and its opening actually improved market conditions on all exchanges. This implies it has negative value.
They also spend millions on hardware, tools and developers to skim small sums of many transaction on the stock market. They are effectively a (very inefficient) tax on the stock market that goes to improving C++ compilers and funding hardware startups.
