You could pose the same question about humans. People are already posting incorrect information all over the internet and consuming that information. In fact this problem predates the internet, people have been writing and disseminating incorrect information for thousands of years. Educated people are trained to be skeptical of what they read and try to discriminate between correct and incorrect information. We're not always perfect at it, but on the whole smart people are usually decent at the task. Presumably the same thing will need to happen for AI, where in order for it to succeed it will have to become better at understanding what information is trustworthy and high quality and what information is less trustworthy.
