Which is true. People are scammed by very low-quality schemes (like that French woman who sent 1 million to the scammers who claimed to be Brad Pitt who for some reason needed money for medical procedures).

Humans have generally a natural wariness/mental immune system response to these things however, and for 99% of people the attention economy is far from being able to completely upend their life or send all their money in an agreement made in bad faith by the other party. I don't see why, if some AI were to possess persuasion powers to a superhuman degree, would be able to cause 100x the damage when directed at the right marks.
