I recall my high school chemistry teacher's response when I was trying to understand why certain reactions happened: "just accept that these reactions happens and memorise them for the test. Don't try to understand it"
I did not become a chemist.
Now I'm in my thirties and I kinda wish I had studied something involving chemistry in university. It just seems fascinating. Unfortunately my teacher at the time did an excellent job of killing that curiosity and when I was choosing what to study in uni my first criteria was "anything but chemistry"
I can't help but imagine how different my life could've been if I had this available to me at the time!
On the other hand this AI could never hold a candle to my history teacher who showed up in full medieval armour, complete with a real sword. He even knew actual sword fighting techniques used by different nations at different times and have approximate demonstrations (slowly, no students were maimed) along with theoretical explanations of the pros and cons of each.
2 of my old classmates are now history buffs: one PhD(dissertation was on the topic of WW2) and one archeologist. That's gotta be above average for a class of ~20 kids.
But teachers like him are a rarity.
