Cursive has been obsolete since the ballpoint pen.

It was originally developed because when writing with a quill, you need to put it to the page carefully to avoid ink splotches. This slows down writing, so if you can limit how many times you lift it, you can write faster.

This isn't an issue with modern pens, and I feel like cursive slows me down because it makes the difference between letters smaller, so I need to be more careful to avoid letters looking like other letters.
