I might be stupid but what are you referring to?

Use your imagination a little; I'm sure you can come up with several variants that are an even viler and more exploitative/manipulative idea than the product as it stands.

Let your kid call a crude simulacrum of dead relatives, let religious folks call a crude simulacrum of $DEITY, make an "adult" version that crudely simulates a phone-sex hotline (charge extra to recharge the minutes on that one obviously), etc, etc.

> make an "adult" version that crudely simulates a phone-sex hotline

This is a quaint almost vintage version of the technology that already exists. Why stop at just audio when you can right now have a "video call" with your AI sexbot? If you were worried porn was going to lose it's top spot for pushing technology forward—and backward and forward and backward—to it's eventual climax then worry no more!

AI powered grandma scammers which can exactly mimic their grandsons voice asking for money.
