Peculiarly, I think your opinion and the difference between the two essays gives credibility to BRs points. One essay by a egocentric multimillionaire, and the other by a man of knowledge and people err on the relative value of the people who make money because that’s what they’re taught to do.
It also explains its points in quite a lot of detail, building a very clear picture of the world and how it got here, pre-emptively dispelling any attack in the style of Chesterton's fence: it not only complains about the negative effects of the praise for work, but also explains why they were initially put in place.
Thirdly, PG's essay is essentially a special case of pretty well known, more general point. PG is essentially word for word stating a common socialist critique of wage work: the alienation one feels when their work is not under their own control, but instead dictated by a capitalist owner. "Finding a project of one's own" is in fact the individualist version of "seizing the means of production".
It's a bit unfair to paint PG as just an "academic". Sure he basically rushed from academia straight into the business world, but he's created things as well. I mean being an investment capitalist will hardly compete with creating ambitious works like Principia Mathematica, but PG has written a few books on the side. Some of his earlier stuff, like On Lisp isn't half bad.
PG has also done his fair share to influence other creators, of course his influence will never be near as great as Russel's, I mean you don't run into a Wittgenstein more than once a generation. While most of PGs influence has been mostly to help other capitalist acquire more wealthy by any means necessary, he was able to help a few very interesting people like Aaron Swartz.
And while PG will never stick is neck out for anyone but himself, worried endlessly about this "intellectual" reputation, you can't expect all creators to be willing get themselves thrown in prison at the age of 89 to fight for what they believe is right.
tl;dr sure PG will never be as powerful of a creative and inspirational force as Russell, but it's unfair to say he's "just an academic"
Peculiarly, I think your opinion and the difference between the two essays gives credibility to PGs points. One essay by an academic, and the other by a creator and people err on the relative value of the academic’s because that’s what they’re taught to do.
