The point is that there are so many different types and subtypes of music that get termed “electronic”. Some of which don’t resemble each other at all, and some of which intersect. The original post has a good article on this.
The area of “electronic work” I am most familiar with is the work being done in universities and other organizations throughout the world in the field of academic composition. I hate to use Wikipedia and these are dated, but to give you and idea of the number of serious composers working in this area: (the second link also attempts to list genres)

Two of my favorites:

Philippe Manoury is a French composer. Manoury was born in Tulle and began composition studies at the Ecole Normale de Musique de Paris with Gérard Condé and Max Deutsch. He continued his studies from 1974 to 1978 at the Conservatoire de Paris with Michel Philippot, Ivo Malec, and Claude Ballif. In 1975, he undertook studies in computer assisted composition with Pierre Barbaud, and joined IRCAM as a composer and electronic music researcher in 1980. From 2004 until 2012, Manoury served on the composition faculty at the University of California, San Diego, where he taught composition, electronic music, and analysis in the graduate program. After retiring from teaching at UCSD, he currently lives in Strasbourg, France.

Marco Stroppa is an Italian composer who writes computer music as well as music for instruments with live electronics. Marco Stroppa studied piano, composition, choral direction and electronic music at the conservatoires of Verona, Milan and Venice. From 1980 to 1984, Stroppa collaborated with the Centro di Sonologia Computazionale of the University of Padua, before moving to the USA where he continued his studies at the Massachusetts Institute of Technology supported by a grant from the Fulbright Foundation until 1986. At MIT he took courses in cognitive psychology, computer science and artificial intelligence.
Go Forth, you seem like the kind of person who might enjoy listening to some of this work! Thanks for posting the link on Nancarrow, who did some interesting work with player pianos apparently.
