Interesting to see how "Bitcoin Fixes This" is setting up to solve other tech problems the Web3 space is failing to solve. Nostr, Synonym, 'Web 5', Zion, TBD, Impervious, Keet and Holepunch all range in how much they interact with Bitcoin. Although Keet doesn't interact with Bitcoin at all, without Bitcoin, the project wouldn't be funded.
Saw a few posts recently suggesting that Bitcoin causes people to do buy Bitcoin and then do nothing, getting rich without doing anything. Hard Disagree.
It will be truly interesting to see how these systems interact. A content creator on Nostr gets a certain amount of LN tips so starts a livestream "spaces" not from a central server, but using Keet instead. Or perhaps if a new relay wanted to backup files from other relays, they could receive the files via Keet as well. (Sorry both examples involve Keet and Nostr, that's where most of my experience is at the moment, I need to dive into the other things still.)
A funny thing about building a world around an internet-native digital currency is that eventually the flaws of the internet start to impede your progress. That's why I think these projects are so important. Let's add more tools to the belt of freedom.
