>And "owning" the first tweet ever sent? What does that even mean??

No, no, no. It's worse than you think. An NFT is more like a plastic cup with Pikachu printed on it. You don't own the rights to Pikachu. You just bought a cup with his face on it. With NFTs, there is no contract to own the actual "thing". Just simply the piece of "merch" (the NFT) with the likeness associated with it. Except, a plastic cup still has value to drink from or hold your toothbrushes.

This is true for many NFTs but not all. For example, cryptopunks, autoglyphs, meebits only exist on-chain. Then there are NFTs like artblocks.io where the code to generate your NFT is on-chain and the output is determined by the transaction hash.
