I saw something interesting the other day that I had previously missed:
Starlink has the potential to provide lower latency around the globe than terrestrial fiber because light travels faster in vacuum than in optical silica fiber.
"Delay is Not an Option: Low Latency Routing in Space"
"We conclude that a network built in this manner can provide lower latency communications than any possible terrestrial optical fiber network for communications over distances greater than about 3000 km."
