Musk was interviewed on 1 Podcast at 1 hour and 49 minutes and talked about NFT.
Lao Ma said that he likes digital art, but he said "it's the funny thing": the thing is not even stored on the blockchain, but just a URL pointing to a small picture.
He believes that NFT should be stored on the blockchain rather than on a centralized server.
It is good for Bitcoin’s native NFT, but does not mention BRC20.
