There's a life outside of mobile
So basically everything is lost because it's not mobile ?
I disagree.
It may take time, but people will come back to (or most of them discover and embrace) the personal computer, because
A. nowadays it's cheaper than a smartphone and
B. It is the better form factor for many use cases.
The video editing software is a good example. Perhaps you took most of your videos with your phones, but it sure is easier/better to edit it on a bigger screen with a mouse, a keyboard and perhaps a stylus.
