My first calculus class was in 2018 or 2019 and before they taught us any of the derivative rules they showed us the first principles derivation, so the fact that they just skipped right to the shortcuts for you is wack. For us it was more of “this is how you find the equation for the slope of a line at any point. But guess what, here’s some rules so you don’t have to do this squeeze formula every time!”
But this way gives credit to Josh for the joke
