Earlier quoted context omitted.
When going through the effort to re-learn how to write, why would one learn this rather than one of the more logical/easy shorthand systems? (To clarify, I mean in this day and age! I would understand if one needed to send 300 letters a day to a non-shorthand reader.)
Cursive is essentially just a shorthand. It is just a standardized way of writing fast while sacrificing some readability. So, yes, now that the world no longer uses crusive that much you might as well pick another standard.
Shorthand is (hopefully lossless) compression technique.
Cursive is a font optimized for continuous use by the human hand and a stylus, leveraging keeping the stylus point on the page between letters of the same word.
It's comparing 7-Zip to Arial.
