I don't think you're right @nemild, it's not a scary quote and it's also true. Sure, people can be duped temporarily but the best quality ideas last. Information is best distributed when it can be distributed freely. What alternative would you propose, censorship, regulation?

Facebook solved a problem (connecting) but it also created one (fake content, bot farms).

Either Facebook will fix it, or if they don't, new products will pop up to solve the problem to try to provide more reliable content.

Recently, might have seen it on here (I forget where) someone trained an AI to try to detect fake news. Sure the first attempts will be crappy prototypes, but the point is that people are trying to figure the problem out.
