Also it’s worth mentioning the “how to distribute content among peers” problem has mostly been solved and has for over a decade, just that nobody has built out the UX for it for a YouTube clone. Torrents exist, #freenet and #hyphanet exist, #ipfs exists, these are all excellent platforms for storing and distributing content without relying on expensive, centralized hosting. Instead, users share the burden of hosting. There’s a whole category of software that solves this problem in different ways (P2P). Unfortunately, every new generation of developers seems to want to re-invent the wheel instead of using time-tested tech that already exists but just needs a UX refresh or maybe some protocol improvements.
If you have a tube site and it says “to skip ads, install IPFS”, everybody would be using IPFS.
