Wow, that video was full cringe. Maybe I am missing the context or something.

Anyway, I really think you should consider NFTs diffrerently, as they are not used for ANYTHING useful right now. NFTs are good because they are immutable.

NFTs + IFPS (which allows mutable data, but will change the hash of data when the data changes) is powerful, especially in a legal context.

Think certification, licensing, medical records. These are things that should be immutable documents, personally controlled, and available to anyone who the owners chooses. This is where NFTs will be useful one day. I know its more mundane, boring stuff. a Projct called MWAT is using NFTs for green energy certification. Take a look.
