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.
