"Fake news, hoaxes, ..., etc." These issues are all symptomatic of people who FEEL increasingly left behind by society. While a small percentage of the population you allude to are probably not capable of separating truth from fiction, far more are fearful of a society shifting any further from what they grew up with. Specific to the US elections, they looked for someone like President Trump to act as a patriarchal figure who would tell them "everything is going to be okay". They WANTED and continue to want the message that they won't be left behind.
Moving yet further into a society of "machine-people" is not going to allay fears at all. To the contrary, it will push them further in the opposite direction.
Missing from the discussion of AI's integration into society is that people want to feel socially useful, part of the pack if you will. It gives them a connection to their society: the feeling that they have a place in it. Taking away their jobs and leaving them without this connection, I fear the consequences of that backlash.
Sorry to stray slightly from the topic, but these thoughts have been ruminating in my head for the past couple of years. While I think AI applied to specific problems will lead to advances in medicine, for example, that will be of great social benefit, I think we need to treat its use in society with kid gloves.
