I firmly believe this is the branch digital cameras are dying on, and at this point, probably must die on. If these opened up, at least to the level iPhone did in 2007, they'd have an ecosystem as people still used them. As-is, for most purposes, my Android phone is a better camera than my full frame interchangeable lens camera.
The smartphone ate the market segment that was previously occupied by point and shoot cameras, not pro / enthusiast camera. I don't think dedicated / non-smart cameras as we have today will die. You will still need dedicated camera for wedding, sports, wildlife, etc. For these you don't need a software ecosystem, you need a robust hardware.
I agree that for sharing to my family a photo of my dog looking cute my phone is a better camera. However for the use case I mentioned, I don't see how I can decently edit a 50 Mpx image on a screen that's not even a quarter of the size of my laptop.
Not to say that better software/feature is not needed though; I would love to be able to do an efficient initial culling/sorting of a given shoot in-camera.
