There are absolutely benefits to software over paper but they feel hamstrung by the constant desire to roll out the next UI paradigm. Sooner or later the set of constraints between device, OS and app versions forces an upgrade. Security updates should be the only reason to even hint at that possibility IMO.
Maybe I’m just too close to the problem. If I squint enough I can see how a pen running out of ink is like an app crash, and replacing the pen/ink has a real, nonzero environmental cost. I’m not sure how to amortize the costs of device manufacture and software development across all bugs, and compare that to the costs/benefits of pen and paper. There is some shade of rose on my glasses, no doubt.
I need more information, but I sense it’s not the kind of information that is important to many people, and especially corporations, to gather.
