they haven't improved on music a whole lot since the heady days of techno and EBM and stuff. And only SOME gear has been improved,
Re: only some gear improving: I'd have killed for something like Ableton Live 10, FL Studio, any of the affordable Roland ARIA gear, Korg, Arturia, or Dave Smith analog gear, etc back when I started trying to make electronic music as a broke teen in the 90s. The gear market for making electronic music with software or hardware in the the 2020s had never been better. I'd agree that most offerings don't sound any better than what was available in the 80s (Serum and other forward-looking offerings notwithstanding), but it's all a hell of a lot more accessible/affordable, and that's important.
Re: the music itself. as we all know, most gear of the 70s, 80s, and 90s wasn't designed for creating genre-specific electronic music... and things like the 808, 909, and 303 weren't designed for making what we'd call electronic music at all, but for musicians to record rock and pop demos to 4-track without a drummer or bass player. Making dance music in the 80s and 90s meant taking a bunch of secondhand gear with extreme technical limitations and subverting thier limitations and intended usage to some degree to make something new and oftentimes transgressive.
Lifting those limitations, and flooding the market with gear and VSTs designed to make genre-specific music didn't necessarily result in an amazing new world of shocking, mind-blowing tracks... but it didn't totally ruin things eitehr... music is still marching forward... great music and awful music seems to get produced at about the same clip regardless what changes happen in the world at large.
The greatest time to be alive and making the greatest music ever is always right now.
