Ethicist Carissa Véliz argues that chatbots that use emojis are emotionally manipulative: without appropriate safeguards, the technology could undermine people’s autonomy.

A 2021 study found that people consistently underestimated how susceptible they were to misinformation.
It would be more ethical to design chatbots to be noticeably different from humans. To minimize the possibility of manipulation and harm, we need to be reminded that we are talking to a bot.
In the long run, ethics is good for business. Tech companies stand a better chance of making ethical products — and thriving — if they avoid deception and manipulation.
