The latency caused by the speed of light around us is so tiny as to be irrelevant. Our reaction times are far greater than the time it takes the light to get to us from anything that could affect us quickly (anything we can eat or that could eat us). If there were another similar-but-faster thing out there, even if it were thousands/millions/infinity of times faster it would give no real advantage. This feels like basically Amdahl's Law applied to fight-or-flight timing. Human reaction time is ~0.25 seconds. Light from even 100 meters away takes 300 nanoseconds to get to you. Those are ~6 orders of magnitude off. If light were millions of times slower, this would stop being true (but then physics wouldn't work anything like the same either, so the point is a bit moot).
