I watched the last episode last episode. I think it might have been the weakest one. Did anyone else go "huh?" when he said "Oh yeah, all that stuff I said earlier about how you can use stimuli and prompts to alter people's behaviour was actually total bollocks"? Something like $600 billion is spent on advertising globally each year, and I don't think that would be the case if the businesses that spend that money didn't see some benefit from it. Ditto propaganda for political parties and candidates.
I also thought the note at the very end about how we can do things differently and avoid the traps of the past rang a bit hollow after we've been told for eight hours that democracy is a sham, revolutions invariably get corrupted and fail, we're all slaves to irrational animal fears and passions that we're not even aware of, much less able to control, and that the mass movements of the past that produced real, positive change are now impossible because we're all hopelessly narcissistic individualists.
