I do not believe that NFT will last for long, trends are always changing rapidly, and what will happen to the future is certainly difficult to predict, the presence of technology that can replace NFT is very large, and I think we have to be realistic if we want to collect NFT.
the thing is, NFT has wide use case that isn't yet to be discovered, it could be used for authenticating documents and etc, NFT is just one of the many use case that the NFT could be taken advantage for.
Although I agree myself these NFT that basically revolves around art just gonna vanish into thin air in the future for the majority of them, it can't be denied that in the future maybe we gonna see a more better use case for NFT than just being misused for speculating arts.
