For me, this video pretty much sums up the problem Web3 has: At every interface to the real world, you need a trusted third party.<p>Another example: A smart contract that transfers ownership of your online accounts to someone else in case of - say - death. Sounds reasonable, but who tells the smart contract that the person died? The coroner? If so, you are back to square one trying to solve the trusted third party problem.<p>Ironically for Web3/etc. the "(no) trusted third party" is both the selling point and it's largest problem.
