The problem the article highlights is not the considerable amount of "graybeards," but the lack of everyone else.
to have a bigger part of that pie, then have more of them jump in.
The problem is: how?
I personally enjoy working with open source projects because I like making code to help other people. But, apparently, that's not enough of an incentive for other people.
Every decision is arbitrary in some way. We, as humans, defined it would be better to arrange the periodic table a certain way, based on characteristics of the elements, but the characteristics chosen are arbitrary. We could've just chosen a different set for ordering, like alphabetical.
Tho, that's a correct (IIRC) yet weird usage of "arbitrary", and since language exists to talk, not to be correct, we might as well not use this definition of arbitrary and stick to what conveys information better.
Edit: I'm wrong! perhaps "correct" was the word I meant to say, not sure tho.
Nobody is doing anything about all the others, and I doubt anyone would like to start against the biggest military force ever
