What I find really disturbing is how dumb and easily suckered we've become while some great information is available readily on the internet, but people won't use it.
With very little effort anyone could be an Einstein now with what is available, but people and kids go to garbage, for example look at a link on youtube on how X gets done by an expert, it will have 400 views, then look at man falls down stairs and gets run over by car on YT and it has millions of views, that and boobies, anything on a 4th grade level or less gets more attention. I taught HVACR post HS for 20 years, in 2004-5 we saw a huge drop off, people had HS diploma's but knew nothing, what's an inch? a 1/4"???? we had just gotten the first HSer's that went 4 years under NCLB, which makes schools pass people. But they're quick with the dumb phone internet search and they find whatever and share it. It became madness because it was next to impossible to police. In HVACR there is a distributor in cooling and refrigeration that spreads the refrigerant evenly into the evaporator, it's brass with copper lines, a question on a test asked about it, one of our students googled it and then shared it with the class, so everyone answered the same thing, that it delivered the spark to the plugs through the rotor to the wires, since they all had the exact same very wrong answer we were able to track it down, but they don't want to try, they want it instant and now, then they go back to spending hours looking at people showing off, committing crimes, boobies, and people wiping out.
We have had to go back and teach feet, inches, fractions, metric, etc etc, it takes time away from learning the trade, the state recognized the problem and instead of addressing it they mandated a certain amount of time and content of math for us to cover or we'd be in violation,
