Efficiency and performance are valuable, not entertaining. My point is that "boring" is a category error for these things, they aren't game mechanics and they have no entertainment value.

I wouldn't go so far as to say there's no viable use-case, but every example I've seen has been a terrible misappropriation. This is largely because they make the mistake of inclusion of an algorithm to somehow be featureful or entertaining. As I see it, this discussion is a bit like ransomware becoming very prolific and people are saying there are no viable use-cases for encryption because it's been used to scam so many people.

To be clear, literally all NFTs are is a key: value mapping on a blockchain. That has nothing to do with finance, art, games, or anything else associated with them at present - the value of a tool is in how it's used. They've been used extensively by shitty people, so now people only know of the shitty ways to use them.
