Keyboards eliminated the advantages cursive had for input speed in most cases, and I find block characters easier to read. Definitely don’t feel cursive has advantages when handwriting speed is less relevant.
The point I'm trying to make is that the preference for block letters is an accident of how most of us were taught, and not intrinsic to the writing style itself.
Teaching cursive is a complete waste of everyone's time.
Actually, I wish I could write block letters more fluently as my (mixed/cursive) handwriting is quite embarrassing!
