Yes. With the advent of typing (and electronic voice-to-text transcription) there’s little need for it. Dissatisfied with my own handwriting, I switched back to printing in high school. Doing so may have caused a slight handicap in writing speed, but teachers who had to read what I wrote appreciated the clarity.
Of course, if individuals wish to cultivate their handwriting as an art form, fine, and for a while yet a reading knowledge may be useful. (It was useful to me in transcribing when I edited a collection of family letters.) I don’t believe the value of being able to write that way justifies continuing to make it a required skill, though.
That’s not the point
It’s a discipline
