My point is though that cursive is far more effective than other kinds of hand-writing. It's far faster than writing block letters or calligraphy. We are "binning" the more efficient method.
But far less effective than other kinds of communication, such as typing.
Being able to write in cursive was important in the early 20th century because handwriting was the primary form by which humans conducted official correspondence.
In the 21st century, it is much more sensible for us to teach our students to get a 10% speedup in their typing than to get a 10% speedup in their handwriting, because when those students are older they are going to spend vastly more time wasted waiting for their fat fingers to spit their little thoughts out onto a computer than pushing their words out via the nib of a pen onto paper.
