I agree with you that now we see this rather as a hype than a useful thing that can be used in business beyond entertainment and art. When this hype is over, we will see recoil again how it was in case with Defi, meme coins and so on with all hypes.
But actually NFTs are capable of many other functions, so when developers start adopting this type of token in different business we will see that NFTs are much more valuable than just digital pictures.
NFT have a lot potential for sure it's just the current hype endorsing NFT as an another useless things but basically it's having lot of potential with wider use case, For example It can be integrated as intellectual property rights and it can help lot of people like creator, writer, developer that more vulnerable to some bad things but beside that it's also can be integrated into various sector in the future, We can just wait for now and let's see what will happen.
