Some in that era could not type, at all.
Yes, and because typists and secretaries were predominately women, it was not as uncommon as one might imagine for male executives to eschew personal computers based on their perception of gender roles.
I like to call it “keyboard cooties.”
And I've read somewhere that quite a fraction of young people nowadays can't type (effectively) on a physical keyboard - no wonder, their main interaction with computing being via phones and tablets. Could be that typing won't be useful/practiced anymore (like already cursive writing in some parts of the world).
