Okay, let’s start with an established fact: I’m OLD. Seventy-four. I’ve watched technologies progress over seven decades. I’ve seen paths predicted that has failed to develop (yet). Flying cars, anyone?
When I graduated high school (and dinosaurs roamed the earth) adding machines and calculators were electromechanical devices requiring either mechanical cranking or access to a wall socket for power. They were out there, expensive.
We sat in classrooms and learned the progression through the world of mathematics – adding, subtracting, multiplying, dividing, fractions, decimals, all before we got through elementary school. Then came algebra and geometry and trig and calculus.
Somewhere in the early 1970’s the handheld pocket calculator showed up and became cheap enough for personal use. This knowledge quickly became a trope in the classroom: “But teacher, why do I need to learn how to add four-digit numbers. I have a calculator.”
And the teacher (back then you couldn’t BE a teacher unless you could add and subtract) would smile wanly and reply, “Little Johnny, what if your batteries die?”
Indeed. I moved from slide rule to scientific calculator, although I kept a slide rule in my desk at work. I used it on occasion just to wow the youngsters.
Everybody at my level in the company had a computer and every computer had MS Office which meant that I had access to MS Excel. If one had some small amount of numeracy (like ‘literacy’ except for numbers) and a few pointers, one could use Excel to perform calculations.
Of course there were caveats: You had to know what you had, what you wanted to have, and some idea of what correct answers might look like. An idiot with a spreadsheet is still an idiot. Give that idiot access to MS PowerPoint and you can move him into management.
Now we have “artificial intelligence”. Ask a question, get an answer, NOW. Somebody (or some THING) has done the legwork for you.
“But teacher, how come I gotta memorize this stuff about history. All I gotta do is ask Alexa or Siri.”
And everybody on that big hump of the intelligence bell curve will be asking the question, supported by management and leadership who are right there beside them on the curve, and they’ll get the same old answers, approved by those before them. No more Edisons or Teslas or Wrights or von Brauns. “Alexa says…”
