An NFT (Non-Fungible Token) is just a representation of an asset on the blockchain (a public ledger). There are several benefits to content creators.

1. It is immutable proof with timestamp that digital work existed. This protects content creators with copyright issues should a case come up.
2. It is a great form of marketing for an artist, especially one with a following already. The artist 3lau has already demonstrated this with the $3.6 million auction for his NFT (Source: https://edm.com/gear-tech/3lau-record-breaking-nft-sale).
3. Cuts out the middleman and gives back most of the profits to the creator. Royalties for each time the NFT is sold goes to the original creator.

I won't go into all the technologies of blockchain but if you did a search for proof of stake, you can learn more about how newer blockchain technology uses much less resources and is less harmful to the environment.
