I wonder how many NFTs, of all those created at the moment, have any value at all, not only to their owner, but to the rest of the community or even to world culture? How many? 0.001% of the total? Less? More? I think the figure is extremely negligible and makes it clear that this technology is extremely crude and not used for its intended purpose at all. How many announcements in the last year have we heard from big and well-known artists that they are releasing their NFTs? It seems that everybody understood that this sector is full of speculators and wash traders and something tells me that the theme of art is the least of their worries.
It's all speculation. Unless governments or serious entities start issuing NFTs, don't expect the trend to be taken seriously anytime soon. Still, it would be nice to preserve the data of NFTs that are truly valuable. Would imagine losing it all if the server containing the NFT data goes down in an instant? You'd say the properties of the NFT are stored in the Blockchain, but without the content, what's the use?
This is still the early days of crypto/Blockchain tech, so I believe there's room for improvement. The solutions are already there to make NFTs last forever. It'll be up to developers and/or NFT creators to do the right thing by using any of the available decentralized cloud storage solutions for investors' own benefit. NFTs or not, crypto won't be going anywhere soon. Just my opinion

Until blockchains solve scalability problems and until crypto users learn to treat these tokens not as a means of easy profiteering, but also to consider their utilitarian properties, nothing in this industry will change. NFTs will continue to be synonymous with scam and spam. Bitcoin was once associated with scam too, but then with the advent of regulation, it began to be noticed by individual heads of state, bankers and large investment managers. Not only does it take time to be accepted, but it also takes a dramatic change in regulation. As long as everyone can anonymously create an infinite number of NFTs, including fakes of known originals, nothing good awaits this industry.
