P2P has miles to go before challenging the reliability, convenience and performance of the cloud. That said, one area undervalued is Partially homomorphic cryptosystems[1], where the cloud never ever gets to see unencrypted user data. I hope the future is fast-local compute on cached data, with the cloud holding a much larger, encrypted but permissioned data store, offering utility functions like search over encrypted data [1]: https://en.m.wikipedia.org/wiki/Homomorphic_encryption https://en.m.wikipedia.org/wiki/Homomorphic_encryption
