I was personally very aware of this when I was a physicist, since most of the work I had to do was writing and working through page after page of equations, which to this day isn't easy to do on a computer. So it was pens and notebooks all the time, and I became extremely particular about which ones I used: a pen which either had too high a resistance or which dried too slowly, or paper that didn't absorb the ink well, and my work would actively suffer.
(Quite seriously: if your hands hurt too soon, you can't write for hours on end. If the ink smudges as you write -- especially if, like me, you're left-handed -- everything is a lost cause. If the paper doesn't absorb the ink and dry enough for you to flip pages in the notebook, you're lost. Any of these things take time, energy, and concentration, and you simply can't vanish into the flow of the science.)
This article isn't about doing science, but about how the ballpoint pen changed handwriting -- but it's through the exact same process. The various methods of cursive weren't popular primarily for their aesthetics; they were practical methods of writing quickly and legibly. As anyone who remembers having to do this in school can attest, that's always been kind of strange, because with modern pens, Palmer-method cursive is much slower and harder: people tend to develop their own semi-script handwriting for when they actually need to write day-to-day. (Except for handwriting enthusiasts who are doing it for fun)
So when you see the lack of handwriting, instead of crying "O tempora! O mores!," realize that what you're seeing isn't simply a move to computers: it's the evolution of the pen itself.
