It's easy to downplay the impact of Facebook compared to the kind of stuff Elon Musk is doing, but it was only last year that we saw dictators being overthrown with the help of social networks like Facebook. That's pretty cool too, no?
I think you are vastly overestimating the impact Facebook had on the so-called Arab spring. Internet penetration in that part of the world is not high enough for social media to trigger an uprising at that scale. Also, just because a dictator is overthrown doesn't mean things automatically change for the better. See Afghanistan, Iraq, Libya, and much of subsaharan Africa.
