Also note that it's pretty hard to give numerical results to a computation on the blackboard. A plot generated by a computer program and embedded on a Beamer slide is optimal in this case.
My handwriting is improving, and I do try to improve. The fact you didn't glean that from my, albeit curt, response is hardly cause for putting words into my mouth. I appreciate the feedback though.
I'm dysgraphic and have typed every school report in since 3rd grade, so perhaps my view is biased on this matter. I remember being unable to learn cursive and my teachers telling my parents "Don't worry, by the time he's an adult everyone will type everything.". Their prediction has held true. Cursive is dead, removed from common core. Handwriting is up next. In my adult life, the only thing I've had to hand write other than my signature has been a few checks.
Forcing hand writing is like forcing modern day car drivers to only take a horse and buggy to work. They could get better at it, but why?
GP actually said: " This is dumb; my handwriting sucks. I'd hate to give a hand-written talk."
