I've pondered this a time or two as well. I think we all, our at least those of us whom worship at the alter of knowledge, seek and long for a variety both intimate and novel that is difficult to acquire; that you can't gain through a quick Google search. There's inherent value there that is absolutely more than fluff. It has substance and intrinsic worth that connecting to a new wifi router simply does not.
However, and before i start I'll say I've been more guilty than anyone else I know, if you get to know some of these people as they transition from "doing it" to telling "stories about it", I've always found the shine wears off a bit. Not that they're weren't tough, or smart, or incredibly capable, but that they were also idiots, fools, bull shitters, and even, at times, questionable characters. They were patently wrong just like the blow hards of today.
I'm not saying that is true for any specific person, your wife's great grandmother, or anyone else's special person. Just that they were all still humans too, warts, flaws, sins, and all.
