The slide rule is a great tool for teaching the relationships between numbers and functions. When all math is done by AI, will people learn why things work or how to make things work?

Do the calculation
I have accumulated quite a collection of calculators over the years, for school, for work, for fun. So long as the modern grid keeps going, they all work. But, maybe I should review the slide rule instructions, just in case. No batteries, no power, no internet. Just works.
Here's a thought: will all calculation be done by AI in the future and, how should that figure in to math education? Teach analog technique.

Because I'm super geeky like that, I've started using a circular #SlideRule when I score #baseball games -- I set the ballpark capacity on the D scale, the attendance on the C scale, and look under the 1 on the D to read the percentage of capacity on C. Accurate enough for my scoresheets.

Just went back and filled that percentage to all the college and #WorldBaseballClassic games I've scored this year.
