teachers, usually from the generation before computers were commonplace
Wow. you must have some significantly old teachers.
Guess what? Pretty much anyone under sixty years old, or even seventy to be honest, has been using computers for several decades. IBM PCs began to be commonplace 30+ years ago, and were becoming ubiquitous a decade later. Apples, Commodores, and Ataris were well known too.
And of course the entire computer industry and the Internet was developed by people now nearing their allotted four score and seven years.
It really is time that we discarded the cliche that old people can't understand computers. It's insulting and inaccurate.
