Splinternet. Wow, that is a very good point. The real scary part is when it gets super, super easy to get on the Darknet. When everything is highly encrypted, and those who want to wallow in hate can do so, to their hearts content, because they will be off into the ether on their own, without supervision, without oversight. Then the only recourse will be full and total government control over the internet. Outlandish as it may seem, it's possible.
