I honestly do not understand the current state of NFTs... I mean, I understand the technology, and I understand what a smart contract is, but really - what is the point of "owning" this tweet: https://twitter.com/jack/status/20 and why would you pay $2.9m to "own" it? Another article (https://www.cnbc.com/2021/03/22/jack-dorsey-sells-his-first-...) tries to compare "owning" the tweet/NFT to owning a virtual autograph, but that still doesn't make sense to me.
What if Jack Dorsey quit Twitter in a rage and deleted his account? That tweet would vanish. Or perhaps Jack gets fired from Twitter, and Twitter deletes his account? What exactly does the owner of that tweet get for their $2.9m?
