The cloud won’t grow quite the way Berin notes, at least not if I can help it.
As the ongoing T-Mobile Sidekick failure shows, if you release your data to “the cloud,” you give up control. In this case, giving up control means giving up your data. (Speculation about what happened is here.)
When you combine that with the privacy consequences of delivering your data to god-knows-where, and to service providers that have heaven-knows-what data-sharing agreements with governments and corporations, the cloud looks a lot more gray.
There will always be a place for remote storage and services—indeed, they will remain an important part of the mix—but I think that everyone should ultimately have their own storage and servers. (Hey, we did it with PCs! Why not?) Our thoroughly distributed computing, storage, and processing infrastructure should be backed up to—well, not the cloud—to specific, identifiable, legally liable and responsible service providers.
