This is not really a yes or no question, I believe.
What I really would like to see is the Linux audio stack becoming more performant and more straightforward to use
*. Not that things are bad as of now, but I am happy to be seeing the RT patch getting Incorporated into the main kernel branch, and I am following this project with some attention: https://pipewire.org/
Incidentally, a more straightforward (to use
) and performant audio stack might be a very significant portion of what is needed to get more users on board.
As far as musicians are concerned, I do believe that windoze is still dominating the share but I think that Mac share in this domain is higher with respect desktop use, so I do not think that the Linux VS Windows comparison is all there is to the story.
Anyway, I do not think I want
more people to use Linux, and by that I mean that as long as people are able to produce the art they want then really they can use whatever they like, from windoze to a Commodore64. Or a tape recorder. I do not have a desire for people to do what they do on Linux just because I like Linux. I don't think of this as a religion to which I have to convert as many people as possible. But of course I would be happy if more people find in Linux what they are searching for.
As a final comment, a possible consequence of attracting users from other platforms is that they will most likely want to try to use the software they are accustomed to. This might mean a lot of development happening on the wine side of things, maybe it could mean more commercial software released for Linux, which as far as I am concerned are positives. On the downside, if that had to happen by some huge number, open source projects that have been around for many years might loose the spotlight and even risk getting abandoned. Maybe. I really do not know, to be honest. Kinda rambling on this last paragraph...
[*] Empathizing to use
because other operating systems are actually not that less complicated than Linux under the hood, but somehow they feel easier to get working and manage. Things do look tricky when you are exposed to the machinery of ALSA + PulseAudio + Jack.
