The entire concept of NFT art is stupidity borne out of misunderstandings about what a blockchain is, and what it's good for.

With time, these misunderstandings will be cleared up, and NFTs as we know them will fade into obscurity. There is no threat to bitcoin here. This stuff will never be viable in a high fee market.

As for the act of putting random data into the chain, using ordinals or OP_RETURN, I think it's kind of cool. Someone called it graffiti on the blockchain, and I think that's a good way to look at it. Sometimes graffiti is cool, and sometimes it's obnoxious.
