Ask HN: How would you rebuild the internet?

The web has been built like a lean startup. It started small as a way to share documents between scientists. And kept growing at a tremendous pace. But because of the underlying architecture, there are some major problems that don't seem to have a solution in the existing web. Like end to end encryption, IOT etc.

If it were up to you today, how would you rearchitect the web (both software and hardware)?
