If people's ability to produce slop outpaces the ability for content delivery and discovery platforms to separate the wheat from the chaff, the category as a whole will diminish.

As a musician I agree that "regular people can make it without sacrificing their soul" is not an indicator of bad music. Some of the greatest, most creative music I had the honor to listen to was made by drunk teenagers who didn't know how to tune their instruments after all.

But the thing about fads: if everybody and their dog knows how to make "proper" punk, low-fi-hiphop or whatever, the result will be bland, uniform, shapeless and generic. That doesn't mean the genre stopped producing great music, it just means you will have to wade through the bland stuff to get through the gold. And few people are willing to keep doing just that.

The problem when a creative niche gets flooded with low quality ripoffs is that people end up fed up with the entire genre.

Plus even that aside, people often crave change. No genre of music has ever remained entirely static. And all styles of music comes in and out of fashion.

I don't know that much about current music, but I do spend a lot of time listening to LoFi study girl live stream, is that music the genre being discussed here? Perhaps it's just the normal hype cycle and then things settle out? Innovation, enthusiasm, copy cats, burn out, a solid genre for decades?

Pop by definition is catchy music and the actual sound underneath is adapts to current trends. It's an ephemeral genre. LoFi is a specific sound and so if people are bored with the sound it'll stop being popular.
