The network would be much faster then local hard-drives. So more data would be stored in the cloud, we are already seeing this transition now because even 10Gbe is faster then most hard drives. With a Tbit network it would be many times faster to load from the network then to load from the computer's own memory. Everything would probably be sent via the network if it weren't for latency. RAM still has some orders of magnitude (nano vs micro) better latency then networks. I'm sure latency can be improved though, even for wireless. As for applications, we will definitively get virtual reality (VR) like in sci-fi movies, with very high res imaging and IO. There are already some crude VR devices and applications, but the market is still tiny. Being able to stream interactively directly to a VR device via the network, to every household - it would suddenly become a huge market. As for file sharing, we would probably ask the network "who has hash-of-file" and the closest device would send it. Or for search, you would specify a category, then query all databases listed under that category simultaneously. No need for a central index. Or something like grep "Under the Sea" com.tech.news.* and everything would be downloaded, searched and discarded if not matched.

Reading this just gets me down. I wouldn't mind if these were phrased as questions but no, we get blanket assertions. > The network would be much faster then local hard-drives. Figures? Are you distinguishing between bandwidth and latency? (no you aren't). How long are reads/writes going to take compared to a local disc: HDD seek times ~ 10 milliseconds, SDD in the microseconds.

I'm no network guy but do you think tying up dozens of routers with multi-gigabytes of data you're going to discard, is free? efficient in energy or time?

That kind of response would be OK if it asked questions, expressed a knowledge of the limits of their knowledge, I'd be ok with that and pointing the asker to relevant material but as it stands, as in that famous quote, it isn't even wrong.
