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).

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.”

These things have a self-reinforcing feedback loop -- consider also for example, men learning to use "power tools" but not a sewing machine.

There's a great anecdote about that in the book _Dealers of Lightning_, where the Xerox execs were indifferent to a demo of the Star personal computer but their wives were ecstatic about it.
