Decentralized Society Finding Web Three Soul

In a paper, decentralized society finding web three soul, Vitalik Buterin talks about soul bound NFTs. He describes how we're all going to have something called a soul wallet that is perhaps higher security and far more important than the ones we can just kind of create a will on Metamask or wherever. And it'll be a wallet where NFTs can be sent to, but cannot ever leave, which would then create an official record of someone's past.
