Modern civilization is at risk.
"Fake news" is just the tip of the iceberg. The internet and social media have nearly eliminated the cost of publishing content. It is now easier than ever for bad actors to spread misinformation for profit or to advance a political agenda.
At the same time, the business model for news has broken. Online publishing cannot support high quality journalism. Advertising on for-profit news sites produces the wrong incentives, often resulting in sensationalist clickbait.
With misinformation on the rise and no model for sustainable journalism in sight, we won't know who or what to trust.
