Um, the airspeed analogy used up front is remarkably silly.
Nobody would shrug at being able to fly 2x faster.
The reason it stopped is because it made lots of noise and was expensive.
Not because it was not needed.
I think you'd be hard pressed to find anyone who would not want faster flights if it could be done at reasonable cost.
If Tbp speed internet was the same cost and effort as Gbps/Mbps internet, obviously faster is better! The marginal returns on speed in most settings drop off pretty quickly.
Yeah I think the level of diminishing returns takes a while to reach when you're taking about flights. I'd be thrilled to drop a 6 hour flight down to 3 hours. Or 1.5. Or 45 minutes. Or 20. Or 10. Or instantaneous teleportation.
But if there are little to no applications for faster Internet speeds -- which for the most part there aren't -- then it just kinda doesn't matter.
