I admittedly don't really understand this in depth but it has seemed to me that there's a need for some general purpose decentralized signature or authentication mechanism. I can see NFTs functioning in that kind of way although I'm not sure the current implementations are the best ones nor has the hype bubble necessarily been focused on best use cases. I wouldn't be surprised if NFTs evolved into something far more mundane, a historical footnote on the way to something else.
