It's not a waste of time. Every time some new thing comes out and becomes popular, everyone everywhere says everything must be that thing because it's the future. In America, everyone wanted pure white sliced bread. People wanted frozen TV dinners. People wanted chain fast food restaurants. People wanted no effort reality TV. People wanted endless superhero movies.
Now people want actual food and they want stuff made with human hands and they want to know what's in it. People want TV shows with a proper story. People are beyond done with cookie cutter superhero movies.
The slop wave is going to pass. AI can make stuff that sounds super polished and perfect, but people will want the rough and crude touch of something hand made. They'll want to see videos of musicians showing behind the scenes of how they made something. They'll want to go and see a musician perform. Interest in 100% AI generated music will fade into the background and it'll be relegated to soulless Muzak used for ambiance in soulless chain restaurants too cheap to pay for actual music and too afraid to play any songs that might offend or annoy someone.
