The persuasion process is based mostly on language - spoken language and written language - but the chatbots that have taken the world by storm are language experts; this is what makes them so effective, so successful, so... persuasive. They can analyze information and then explain it, they can examine our texts and then improve them, they can write texts themselves. This is the reason why as these models become more sophisticated, the concern about their persuasive ability grows. At first their level was similar to that of high school students, but what happens when the high school student becomes a professor, what happens when he becomes a professor within two years? On the other hand, many don't understand why this issue, of the persuasive machine, why it disturbs so many researchers, experts and developers so much; so what if it persuades, what's the problem? I didn't think there would be a third part to the series but here it comes: Oh Shit - Part 3 - The Persuasive Machine.
