Someone who's lived with something for 50 years and then suddenly it disappears and gets replaced by something else that they don't understand will usually not like it.
But I find old people less fussy about technology now than they were 10 years ago. When I was younger in a lot of cases it nearly only children using certain technology. Like it used to be nearly only teenagers/young adults using social networking sites (like Myspace which was biggest at the time), but nowadays I see lots of parents, and even grandparents using Facebook.
It's a BIT EXTREME though that your teachers prefer horses to cars.
