Among the many thorny issues and questions raised by Cohen:
* The business model of social media companies is powered by engagement, which is greatest for content that arouses the basest instincts and feelings of human beings, including fear and hatred. Social media companies earn more with the basest content.
* Social media companies are ideal propaganda machines, enabling anyone willing to appeal to the worst in human nature to reach billions of people with a click.
* Do social media companies bear responsibility for the negative impact their products have on society, in the same way that, say, car companies bear responsibility for faulty engines or airplane manufacturers bear responsibility for faulty plane designs?
* Are social media companies publishers, like broadcast TV networks, magazines, and newspapers? Should social media companies be held to decency standards, like all publishers?
I'm barely scratching the surface.
