There are some very interesting technical challenges that NFTs are being used for. Stuff like baskets of assets, appraising and taking out loans on assets, and certain distributed games like aavegotchi. At the end of the day, representing non-fungible assets is something useful. It's just that most people's exposure to it is seeing someone riding the hype to sell something that would probably have sold for a lot of money without being on the blockchain. Nothing wrong with that either if both sides are happy with the deal.

There are a lot of interesting technologies being worked on in moving real world data on chain as well. I'd highly suggest you look into chainlink. They cover all sides of the vulnerabilities associated with getting accurate data when you could be trusting a potentially malicious data provider.

I wish hn would cover some of these more often
