Cursive exists not because of quills and ink but because it’s easier on hand muscles when writing long form.
People used to write hundreds of pages a week. The letters I sent to friends when I was in college were probably 20 or 30 pages each, and several went out each week.
Writing that much in print hurts my hand, even today. Last year I switched back to cursive in my daily work notebook and it’s reduced hand pain greatly.
