Should be afraid.. If people are more convinced an AI is human than a human is human, that means AI will be more likely to convince you to adopt their 'point of view'.

To put it another way, if an AI and a human post two different views on a subject, people are more likely to be swayed by the AI's point of view.

So for much cheaper now organizations can use AI at scale to sway public opinion in a way thats more effective than ever before.
