Scott, you reminded me of my old Uni teacher. She was The Queen of a Slide Rule and her nickname was Bloody Mary. She was a true Slide Rule virtuoso and we were hopeless. Her calculation speed was just jaw dropping, and we kept making mistakes all the time. Then one day suddenly ( literally within a week or so) everyone got a calculator. And the slide ruler was dead. She was devastated, because as a teacher, without a slide ruler, let's be honest, she was quite poor. She even tried to convince us that a slide ruler was good for our brain, unlike that stupid electronic calculator that makes no mistakes. Predictably, poor Blody Mary was left alone with her Knowledge. Probably she thought we were a lazy generation, always looking for shortcuts, trying to do things with the minimum of effort.. Unlike us she was not excited by the fact that a calculator works million times faster than any slide ruler and never ever makes mistakes. Probably she would say that a cube root of 267549, calculated on a ruler, would have a different smell and color and ultimately is more human..
I still have a couple of slide rules somewhere. I couldn't use one now if I had to because I was quick to embrace electronic calculatorsThe first engineering company I worked at had some old mechanical rotary calculators that would do simple math but the user had to figure out where the decimal point went. Better than a slide rule but not by much.
I think it goes a bit deeper though. Most of the old(er) guys here will remember taking things apart when they were a kid just to see what made them "Tick" (I still have parts of a Micky Mouse watch I took apart when I was 6). Vacuum cleaners, clocks, anything mechanical was fair game if I could find a screwdriver and pliers.
Maybe I'm wrong but I don't think that kids don't do that now. Want to know how a vacuum cleaner works? Google it and use the knowledge that someone else gained. Want to see the insides of a watch? It's on the internet somewhere and you won't wreck a watch looking at it. My point being that there is no urge to obtain knowledge for one's self any longer. There is no urge to "Tinker" with things and see how they work and how to make them better. Everything is "Canned" and already there for the reading. They don't understand that wrecking the watch to see what made it work was the fun part.
Well I hope you'll forgive me and understand that this isn't an emotionally driven response but I'd have to say that's an over generalization. I have a nephew that absolutely cannot resist tearing apart anything that has moving parts. He constructed his first racing lawnmower just last year. He is keenly interested in how things work and what makes things tick. I don't think that's generational, I think it's more personal. Me I'm more interested in getting things to work - so if I can google it and figure out a quick fix, yes, admittedly I will.
