Ask HN: Where's All the P2P?

Everyone is talking about how everything online is too becoming too centralized and closed off all the time.. I'm seeing lots of "self hosted"* projects, but almost nothing seems to truly invite user-participation when it comes to hosting.

Remember filetopia, kazaa and napster?

When you used it, your computer became part of it. Why can't we have this with non-piracy oriented services?

Why is peertube a collection of disconnected, hosted instances, rather than something every user is actively participating in hosting?

I'd much rather see a peer-tube client prorgam that I run on my computer and say "here's 100G I contribute to the network, go use that for whatever is needed" than a number of slow, weakly connected "instances".

With such fast computers, so much storage and so plentiful bandwith, it seems almost insane to me that the Internet is still mostly a bunch of privately-owned webservers in datacenters, rather than the fabric of a truly user-hosted and user-run network.

[*] Where self-hosted means "pay a cloud provider to host it for you.
