On one hand, they bring a wave of innovation and open up new ways to use the Bitcoin blockchain beyond just financial transactions. People are experimenting with art, NFTs, and even data storage directly on chain, which some might say adds value or relevance to Bitcoin in a more creative context.
It's not innovative or new. Older protocol/idea such as OmniLayer and Colored Coins already let you create token or NFT. And to store data, people already can do it using OP_RETURN directly.
So, are they good or bad? I’d say it depends on how much you value innovation versus purity.
People could just one of Bitcoin layer 2 or sidechain for those purposes (NFT, token, data storage and other non-financial usage), so i would say it leans towards bad.
