While I fully agree with you, I don't really fret the masses being manipulated. It's shitty and scary, but time immemorial we've been sewing these threads among each other. In a pretty recent post someone outlined that any time there is a new form of communication, we get a pretty big wave of manipulation (printing press --> reforming the catholic church / broadcast TV --> 2. World War). We got this current batch of Brexiteers and Trumpists because the internet makes for amazing echochambers. This will just be an escalation of that (yeah, not as reassuring as I'd hoped it would be).

I'm more worried about me being (mis-)led by my nose. I think I'm losing my edge.
