All the web3 talk is scoffed at by many, but I believe in decentralizing the internet as much as possible and am a big fan of Bittorrent.
To quote Satoshi Nakamoto, "For transferable proof of work tokens to have value, they must have monetary value. To have monetary value, they must be transferred within a very large network – for example a file trading network akin to bittorrent."
I don't believe BT will truly take off until web seeding is functional in all clients and I can use (a site | series of sites) to make a torrent of an existing thing. There was such a site (whose cute URL escapes me) where one could plug in a URL, it would download and cook a .torrent file but with the web seeds pointed at the source, and from that point forward others could get the cached version and the process was bootstrapped
I was also saddened by AWS dropping torrent support from their S3 API because that's one more easy way that folks could provide torrent bootstrapping "for free"
