I wonder if many years from now, when the history of the 21st century will be told, they’ll say it was the era in which technology first enabled human ignorance to self-organize on a global scale.

There have been, of course, many institutions that relied on stupidity and ignorance to flourish. Many religions, for instance, may have capitalized on human stupidity, ignorance, and prejudice to flourish. But the organizers themselves tended to be very smart, and religion always needed the support of smart people to stay in power – to keep the institution running. I think the internet has created an infrastructure that allows ignorant people to self-organize without any smart supervision.
Note how all around the world, fringe groups of highly uneducated and ignorant people – people who are largely immune to reason, have gained enormous power on the internet: White supremacists and Neo-nazis, racist Pro-Brexiters, the anti-immigration crowd, the extreme right in Israel who label anyone who wants peace with the Palestinians or dreams about the end of occupation a traitor, but also groups on the left like Occupy Wall Street and Antifa. There are a few interesting commonalities around these groups:
  1. They seem to be grassroots, often starting through a viral post, or an emotional reaction to an event. 
  2. They feature a very strong appeal to emotion, but have an almost total lack of educated or intellectual support.
  3. They tend to be purely destructive – there is often no attempt to create anything new, no clear agenda, no clear and considered plan.
  4. As soon as there is an attempt to form a cohesive agenda, by someone who is a bit more educated or intelligent – the fizzle out.

I’m not necessarily married to the term “stupidity” here – but I do think there is clearly a new phenomenon at play here, that of self-organizing *without* an actual organization, which necessitates thinking, planning, or capable educated people.
