NFT's are extremely damaging to the environment and Tbh, stupid AF.

It’s currently enormously energy inefficient – estimates vary widely, but best guess is that the average power consumption of a single transaction is equivalent to about 48kWH of energy, or something like two or three days’ worth of power for an average Australian household. And a single crypto marketplace, of which there are many, submits thousands of transactions every single day.

NFTs, or non-fungible tokens, are unique files that live on a blockchain and are able to verify ownership of a work of digital art. Buyers typically get limited rights to display the digital artwork they represent, but in many ways, they’re just buying bragging rights and an asset they may be able to resell later. The technology has absolutely exploded over the past few weeks — and Winkelmann, more than anyone else, has been at the forefront of its rapid rise.

NFTs allow you to buy and sell ownership of unique digital items and keep track of who owns them using the blockchain. NFT stands for “non-fungible token,” and it can technically contain anything digital, including drawings, animated GIFs, songs, or items in video games. An NFT can either be one-of-a-kind, like a real-life painting, or one copy of many, like trading cards, but the blockchain keeps track of who has ownership of the file.

So someone can buy and own the rights to let's say Streets of Rage 2 Soundtrack and SEGA would have to pay to use it in a future port? This is really confusing.
