Honestly, since directly after the dubstep craze era, there has been suuuuuuch good music, because I feel like that's when electronics became much more mainstream for ALL musicians to play with. Prior and during that time, I think a lot of electronic music was about experimenting with sounds. But during that era I think was when everyday musicians got comfortable with the soundscapes, and started incorporating all their other music knowledge and to make more varied, complex, and interesting stuff.
The problem is just finding the good music, since it can be so quick for anyone to produce and distribute it. There's just way too much.
? I mean I'm not disagreeing with you. Each of these step changes increased the usage of technology dramatically. I'm not really naming dubstep as the instigator as much as much as I'm just using that to describe the general point in time where I felt like computers became more prevalent as the defacto composition tool. I feel like this is around the time where computer music has really evolved in usage in all genres. For example, the amount of computers in new orchestral scores right now is wild. Of course it was used long before this, but there's a big difference between usage in specific genres and/or to make music stand out, and it being a part of the general palette for every genre.
Personally I feel your view is too constrained to your own timeline and experiences and is discounting the spread of technology in music for at least a century.
I mean, that very well could be so! After all, I've only lived during my timeline, so recency bias probably does make changes seem more dramatic 😂 . But I do feel like computer usage has created a pretty significant change in how music is composed and produced compared to prior technology, and a lot of those innovations are relatively recent.
