>ERC-721 is the standard that dictates how one should create an NFT. Each ERC721 NFT must have a tokenURI field, that is an external link to a JSON file stored on an external server ... You can notice the image field, which is a link to an image.
Not just a link, a link to a link! And when that server goes down next year, all those JSON files will vanish.
