The ability to use it is now out of the bag, and people will use it as they see fit, while I personally don't see the point in these collectibles if people want to waste their money buying, creating, and trading them so be it, its your bitcoin you do with it as you please
I do think that NFTs only became popular on other platforms because your native token can be spin up to pay for it out of nothing, there's a real economic cost to wasting bitcoin on silly transactions and I think the market figures that out with time
I don't see this stuff going away anytime soon, but i do think it will fall to the histroy books the same way as things like satoshi dice and counterparty did before
