Essentially, we built personal computers -- single user, application oriented. Engelbart started with and imagined an interpersonal computer -- all users, data oriented. Those are fundamentally different approaches; one in which systems are isolated and the other in which there is only one system; one in which data is in a standard interoperable semantic format, and one in which files are bags of opaque bytes. It's going to take more than some time for the two to converge, if they ever do.
