There’s a lot going on here:
Do you ever feel like you’re using the Internet as a modem? […] The Internet is actually an awesome modem. The online services blow AOL away. But are we really that far from 1995? […] Can we re-decentralize the Internet? A lot of great hackers have tried. Maybe we can’t? Maybe it’s just impossible? […] The Internet isn’t from 1995. It’s from 1975. In 1995, we learned that a network beats a mainframe. Now, we’ve learned that a 2015 mainframe beats a 1975 network. […] Does it beat a 2015 network? What is a 2015 network, anyway? […] If the Internet beats a modem, and a modem on top of the Internet beats the Internet — what if we made an Internet on top of the Internet? […] These questions seemed interesting. So we built Urbit.

The Hacker News discussion starts off sophomoric, but gets better.
Best promo slogan I’ve seen yet (from this, last year): “If Bitcoin is money, Urbit is land.” It’s the algorithmic propertarian matrix for virtual real-estate.
