@TruthSandwich @freemo @Pat I've seen a Mathematician mock students for using calculators. He went on to point out how hilariously bad the slide rule was in comparison. He concluded by saying that calculators are superior and that the slide rule was more heavily utilized than the modern calculators. IE he implied that the use of calculators helped to decrease reliance on calculations that were now more commonly done by hand.

There's something unique about Mathematicians pointing out how things used to be and how they are currently. The unique thing is that they usually despise both. Calk was an instrument and it left a large mess. Dry Erase markers work well when it's the second or third one that one grabs and the solvent hasn't evaporated. Points to the floor and points out how it's like chalk but not airborne. Then uses a digital board and mocks how inaccurate the stylus is even after calibrating it several times.
