I suspect some of these arguments, are as old as music itself
some classical music devotees will tell you rock/pop is not music.
there have been some great discussions around this on the lines community, this is just one (of many)
... I think Ive seen similar discussion on muffwiggler etc, I think electronic musicians do worry about it, which is interesting in itself.
of course, some electronics will make music making 'easier'... e.g. you don't need to practice for months, to get a single note (like a violin)... but making music more accessible is not bad!
(even this, i suspect is a demographic thing, look in africa, or the middle ages, many just pick up rudimentary instruments and just 'play', they don't/didn't need gear)
historically, music making was a social thing, and not high art, so why be 'pretentious' about it, its a form of expression/creativity... its one form of 'art', does it matter the medium you use to do this?
I will say there are some flip sides...
probably my biggest bug bear - DAWs, Grooveboxes, keyboards - really tend to 'push' people down the 4/4 , 120 bpm, 12 note western scales. sure most can be changed, but the defaults mean we all get comfortable with these when we start - which is when we are at the most 'vulnerable' to influence/setting patterns. so you have to make big efforts later to break this. (all compounded, by so much music we hear follows this)
with a traditional instrument, you have to practice it for many months/years... so you build a huge relationship with it, an investment.
with electronic music, the temptation is to flip between different synths/daws/controllers... and we just don't have the limitations/boundaries, there are so many possibilities, its almost stifling.
put another way, guitarists tell me they are still 'learning' after 15 years on one instrument, do we have that kind of focus/relationship with electronic instruments?
Roger Linn (and others Lippold Haken et al) have been saying the art of expression is lost in electronic music. Roger saying we almost have lost the 'solo' due to this lack of expression.
Its all down again, to grids / keyboard being 'black and white'... not being able to play 'in between', having 'too much precision' (adding 'randomness' to make more human is kind of missing the point)
this is why Im a real fan of expressive controllers, these let you get back that performance/expression side, and reward practice.
its very easy to get caught up in the programming, the upgrading , the GAS for new gear.
sometimes I do think , sell it all, and just buy a piano!
I will say, I fall foul of all of these 'flip sides' even though I try to consciously avoid them... but the upside is this area is its full of possibilities... avoid the 'traps' and the creative possibilities are unimaginable.
apologies for long post, but I think its a fascinating topic... and one I love to read about, as others posts on this, have given me huge insight into 'what is music', and a way to help me think about my relationship with it.
all said and done though, if your having fun, enjoying it... then I think everything else is irrelevant.
(unless of course your trying to make money from it )
