The speed of light is rather unaccommodating.
We run into human-perceptible relativistic limits in latency. Light takes 56ms to travel half the earth's circumference, and our signals are often worse off. They don't travel in an idealized straight path, get converted to electrons and radio waves, and have to hop through more and more hoops like load balancers and DDOS protections.
In many cases latency is worse than it used to be.
as you point out so vividly, the speed of light is actually not a problem given you can ping across an ocean in sub 100ms (not a laser beam, actual packets through underwater pipes). 56ms is acceptable latency for realtime video
