The science is clear on human's capacity for meaningful/real realtionships (it's a pretty small number), the anecdotal evidence is also fairly clear on FB's real contributions to society (it's not positive).
FB really is the poster child for just how willing we are as a species to roll around in our own feces. It's most definetly a sad commentary on where we are at in general as a society and the contribution it made to the last electoral shitshow is just icing on the cake.
Hell, it's also sigularly unsurprising that Zuck is headed to politics, in fact that morass of crap is just about a perfect fit for him.
