So - I don't disagree with much of what you wrote. I write per what my relatively modest needs are and believe that things are better now than they were.
For instance, For most of just over 25 years I've been keeping a hand-printed journal since 1986. About two years ago, my hand began fatiguing faster, and I could not find pens with a wide enough barrel to help. (And at some point a too-wide barrel would prove equally problematic, yes?) I'd been reluctant to go to a keyboard since I connected with pen and paper much more intensely than with keyboard and screen.
But, alas, my hand just couldn't keep up with my mind. Not that I had anything profound to say - just that what I did have to say needed written expression.
A few years ago, Word would not have supported what I want to do. Now it does so easily. And there are third party programs that make transfer of images to and from Word child's play, e.g., Snagit. So my Word document can be almost (not quite) as visually rich as a hand-printed page with doodles, drawings, things overlapping, crossouts, etc.) It's not as much fun as it used to be, but it's sufficient and getting better as third party software makes some things that were difficult easy. Example: I just found a music keyboard for my Galaxy Tab. It records music ideas I have and I can then send them via Dropbox to my PC where I can then import the music into Harmony Assistant which will score what I played. I can then take a screenshot of the score and paste it into my journal. And I can annotate it such that Ultra Recall can find the relevant document when I need it.
All that would have been darned near impossible for me (not a techie) just a few short years ago.
Given the synergies that are out there, and again, assuming the free market doesn't get mucked up (I'll accept that we need not identify "by whom"), the incentive to keep on moving things toward richer digital environments will continue, and people like me will benefit from this.
Here's a digital environment that I would love to see come down to level where someone like me could afford it both in terms of price and ease of use.

And I believe one day, environments like this will emerge for the everyone.
Hopefully, I'm not too optimistic.
