I like non-fungible tokens. The jpeg stuff made no sense but the composability/interoperability is awesome, making items in one application that anyone can integrate into their own applications without restrictions. One developer can make a game where you can destroy your items from other games without the origin game having any say in it. An open API that no-one controls.

Remember CryptoKitties? The first NFT game before it was called NFTs. Someone made a game where you bred dragons, but in order to do so you had to feed them CryptoKitties. That's the type of stuff I like, not the play-to-earn crap.
