Ever? Yes, of course. Right now ? No.

10Gbit/s Internet connectivity sounds like a lot, but it's only 10 times the speed of what we have now.

Think about RAM, CPU frequency, non-volatile storage, and graphical rendering capability these have increased orders of magnitude, as have Internet connection speed.

I don't know what it will be used for, but I'm certain that new use-cases will reveal themselves as that speed becomes broadly available.

It will certainly allow new business models, for things like storage of raw video and video editing, but broadly, I think it's unexplored territory.
