I like the note about privacy. I believe it -- we need to push for a transparent society. Certain activities will always be easy to do anonymously, but certain capabilities are just founded on identity persistence. I'm curious if there could be a framework that has great persistence of preferences and identity, and maintains anonymity.

Another note: it's all just software. That makes it easier to acheive if you integrate systems. It also limits reach. You still need to move your ass from point A to B to C. Most of the time, you'll need to pay attention while doing it -- automated driving isn't part of web 4.0.

Also, there is a ton of legwork involved in services. Many services demand people behind them. It would be nice if humans were only needed to thing -- to have and share desires/preferences/thoughts. Right now, only a minority of people have the luxury to do that full-time.
