My argument has always been about access. Some kids are lucky enough to be brought up in a household with music all around; the internet makes it possible to any kid can surround themselves with brilliant music and musical knowledge. That's all. There still has to be a will to make music (or art, or tech, or whatever). It's just an enabler, a lever that wasn't accessible to most kids in the past, is all I'm saying.
Not so much tech per se (although I also like your point about apps for music practice and other things) but the social changes and prosperity that are partly driven by tech.
