It's a useful piece of information but for something that argues against the hazards of technology and media, it has a lot of bells and whistles and a very clear intent.
I found it particularly interesting when one of the interviewees used the introduction of the bicycle as an example of how tools previously didn't work against us. He has no basis for this. Bicycles were considered a corrupting element. They were one of the things that encouraged pants for women and public misbehavior. Coffee and hot chocolate shops have, in the past, allowed for crystallization of political opinions and led, in part to revolution. This may be worse (not sure. I wasn't alive then to know) but it is not unique.
The point is, the documentary argues that we're uniquely s*##wed because thinking that makes us feel special. It's encouraging positive feelings towards it to get publicity because that drives traffic to Netflix. In arguing against controlling the flow of information, it's doing it.
