Just from watching the video, they're not exactly saying the existing internet is broken, they're confusing terms.
They're claiming the web is broken (that is, tim berners lee's http web), the hardware-internet-network is fantastic (that is, all cables, routers, everything but the software layers).
For some reason, they also claim to dislike tcp/ip.
All I can gather from their video is that they're trying the internet again with a different approach (built-in encryption, tools to far more easily build decentralized applications, your data is yours, and a point about API stuff that I don't quite grasp yet.)
Their goal is to be a self-governing digital republic, whatever that might mean.
As the guy says in the end, it's not up to them what urbit will become, it's up to us (the people who develop for urbit).
That's how I understood their video
Soooo... I'm not too sure why building (arguably?) better tools would result in a "better" internet. Additionally, I'm not too sure what the advantages are for end-users for decentralized applications.
So to conclude, it's up to the developers to find valid use-cases for urbit. Just like how it's up to developers to find valid use-cases for ethereum. Decentralized toolchains (like ethereum, other blockchain-things and urbit) are in their infancy, nobody really knows if they'll sprout useful use-cases or not.
Tl;DR Experimentation and uncertainty
