I think a more interesting question is: what if internet protocols and routing equipment were designed from scratch today? Besides much larger packets, I'm guessing something basic in the style of UDP would be chosen to replace HTTP to simplify query-response lookups, a much simpler streaming protocol would be chosen to replace TCP and support all the video playing going on, and those two protocols would more efficiently handle the vast majority of traffic.

There have been a few of these types of discussions on HN -- search phrases like "internet from scratch" -- really fun reading.
