This is true, but also misses a bigger point: in the particular case of low latency trading, once everyone has similarly fast network infrastructure, the only place left to improve is the time spent executing the algorithm on the CPU. Certainly not all strategies are so latency-sensitive, but for those that are, even a small speed difference there can have a significant economic impact.
