all acoustic music isn't classically great art, and most of it is absolute dreck - welcome to the marketplace - and the same is true of electronics...but , it's a helluva lot easier to play an electric keyboard or guitar than it is to play an acoustic, and that aspect of things enabled far more people to play, and create, than was the case before...
for one obvious example , instead of going to the conservatory and learning theory and practicing for years, almost any kid could form a garage band and instantly "play", and punk rock wasn't the only result...women played electric guitars, at least in part, because you didn't need brute force or have to wind up with bloody fingers if you didn't have the strength to hold frets down properly, and keyboards that respond like butter and don't demand fingers as thick as sausage are much easier to learn, and play...
and back in the day, stereo was called artificial, because it didn't really duplicate what non-recorded music would enable one to experience in a real, live performance...big deal, let's throw out all the wonderful music and song we have on stereo because it is, really, so cold and unreal by comparison to live performance? how many people ever get to hear any live music? or any other performance, for that matter? without recordings, tv and other aspects of "the work of art in the age of mechanical reproduction", how many people would be able to share in what some would call "art", at all?....
of course, stereo buffs in those days were often nerds who loved playing sounds of railroad trains and jet planes as much as music, but the point is that these advances, while mainly providing an excuse to saturate the market with more garbage, also, contradictorily, enabled a much greater, more democratic possibility for people to hear, play, participate in appreciating and making music...and so, a vote for cds and digital, obviously...but....
old analog tuning was much more fun than digital...you could turn-slide the dial and pick up all the in-between stations, static, sounds, while with digital, you punch in a number and get that exact spot on the frequency wavelength, without the "play" that was once available, and which provided great fun, and even creative endeavor, to far more than john cage...the same is true of analog-lp scratching, which is so far impossible to duplicate with cds...but give people time, we'll figure something out...
but be thankful for the larger favors, though in an ideal world i'd prefer to have both analog and digital tuners...but goodbye lps, and good riddance to the slavery of the needle ( except for djs, of course)...
as for instruments, the more the merrier, and the more available the better, whether acoustic, electronic or simply air guitars and keyboards...
