> As a relatively old person, at least for HN, I don't believe it's ad hominem to suggest that old people don't understand new things as well as younger people do.

As a pretty-young curmudgeon, I will say that young people often throw out "he's old and doesn't understand the internet" when they really mean "he's old and doesn't share our values re: the internet." "Neutrality" is a value you subscribe to, not a technology to be understood.
