Wouldn't be so sure. True, heavily inflated and manipulated JPEG market will probably crumble but I think that NFTs will become an important part of for example gaming industry as "play to earn" is becoming a thing now. And when you take into consideration that gaming is by far the biggest entertainment industry (bigger than a whole movie and music industry combined), no wonder that games that are using NFTs are popping left and right. Vast majority of them are still browser-style crap, but soon AAA stuff will start coming out, when major game studios realize the potential to make even more money that way.
NFT doesn't bring anything new to gaming, game companies like Valva have been allowing players to trade their items for real money for a long time already. Gamers don't care whether their stuff is stored in centralized database or on decenetralized blockchains, they just want to enjoy the process. "Play to earn" will never be popular, a large precentage of gamers are middle class people who absolutely don't need to collect pennies for hours of repetetive tasks.
