What happened with cigarettes? Same must happen with chat bots. There must be a prominent & visible warning about the fact that chat bots are nothing more than Markov chains, they are not sentient, they are not conscious, & are not capable of providing psychological guidance & advice to anyone, let alone those who might be susceptible to paranoid delusions & suggestions. Once that's done the companies can be held liable for promising what they can't deliver & their representatives can be fined for doing the same thing across various media platforms & in their marketing.
