I do think that's worrisome to some extent, but I don't think it's novel. All those issues exist already. Those automated systems aren't going to do anything to you that an army of click workers from a call center in India or fishing groups aren't doing already.

Whether you're being defrauded, mislead, scammed or your election or attention is stolen by bots or an army of trolls in a basement somewhere really doesn't make much of a difference. The problem is the same, mass communication allows attacks on people at low cost on a large scale. Human or robot, doesn't matter much. In either case skepticism and literacy are the answer.
