Also, I think you have to consider the role and huge influence that the enormous rise in home studio hobbyists have had on today's music. Before computer-based music production became widespread and affordable to just about everyone, there were a relatively small handful of people who could afford to make synth-based music, so their influences were dominant (not to mention that huge music labels dictated the music market). Nowadays, the financial barrier to entry is all but busted down, so just about anyone with a computer, a DAW, and some decent monitoring gear can crank out a dancefloor-ready hit if they put in the time to learn the craft. In some ways, it has become the modern version of folk music. It's hard to say if things would've played out the same way in the absence of computers and MIDI. Couple that with the huge boom in independent labels that arose from the number of independent artists making music and the number of streaming platforms that computer technology has created. It's opened a lot of doors for people's styles that might have never been heard outside their bedroom. But, it's impossible to say if the same thing would have happened without computers, or at least at the same pace.
Anyway, it's an interesting question for a complex situation and I'm personally just glad that progressive synth rock made by dudes wearing capes never became the status quo for electronic music.
