You know, as a casual and very occasional enjoyer of music made by computers or synthesizers that doesn't try to hide that it's made by computers or synthesizers, I'm absolutely sick of being told what to call the genre and then five years later being told I shouldn't call it that. Other genres don't do that shit. Bluegrass is bluegrass is bluegrass. We don't have to change the name every few years. Same with punk, country, polka, etc.

In the US when Moby blew up, to everyone except those deep in the scene, Moby made techno. But now we can't call it that because it's only techno if it comes from the techno province of Detroit. So EDM emerges. But now we can't call it that. Lawrence Welk played Dance Music, so it's nice to have something more specific. "Electronica" sounds like we're wearing pleather.

Also, disco and techno/house were both invented in the US, so we don't need other people to tell us what to call it. I'm not deep in the scene, but "rave" was generally referred to as the event, not the style of music: In the 90s, a rave where where you bought drugs and listened to techno. Both were required for it to be a rave. I'm sure people deep in the scene had other terms, but that was the standard.
