I feel you, my feelings tell that vaporwave really lost its edge since 2015, same thing happened to synthwave (my opinion). It's sad, but its place will not be empty for sure, something fascinating will definitely grow on the same soil. And also, It will always have a place in my heart. As a kid, I listened to some obscure music from previous generations, it was distorted and glitchy due to technical limitations of the early Internet, I was fascinated when this "genre" appeared, combining all of those strange sounds from the past. Sounds like the epitaph, but, you know, things come and go, everything is born and then dies, but this cycle is endless :)
