Knew a fellow high up in an old tech company.
He described a conversation where some clueless executives were dissatisfied with the time required to get data to the other parts of the planet.
The tech execs wanted to know why the engineers were not working harder to lower latency to *zero*...
"Well...errrr...
Because of the speed of light.
Because the universe won't let us."
Oh, that reminds me of a vacation at a rental house, isolated along a tiny dead-end road on the side of a river gorge.
V-shaped deep ravine, and the only possible internet service then was a dish pointing up to a geosynchronous satellite.
Latencies were large enough, that some stupid language-learning app on my phone would balk on the delays, when it came to the speaking exercises.
