I already know when my dogs needs to eat, drink, shit or pee or go for a walk or play because he usually will tell me.
Choosing to ignore your dog won't change because some magical AI can now translate it to -Im fine, Im only barking because you're an awesome being, keep your subscription humaaan-
But can your dog (translator) say "I love you?" In a doggy-voice? Replika proves people will pay for this and convince themselves it's real, because they want it to be.
