Good for you that your school was willing to adapt to your needs, but surely that was not the norm for millennials when they were in school. I never went to school in the US but I don't believe that classroom activities (tests, note taking, exercises, etc) were normally done on computers in the 90s/00s/early '10s...

So why did those kids stop using cursive, at a time when hand-writing was frequently needed? My point is that it can only have been taught wrong if it was not legible or fast enough for most kids to see a point in using it.
