Agree to an extent, but not all money in quant finance is generated through HFT. Notably, I don't think funds like Rentec are really doing much to get low-latency [1]. Latency obviously does matter for any kind of quant trading, but to my understanding a good enough strategy + slippage models & the likes can overcome this.

[1] You can find a list of NYSE broker/dealers here: https://www.nyse.com/publicdocs/nyse/markets/nyse/members/NY... -- any firm where latency matters will need to be on this list to colo on the exchange.
