I'm counting mothers/parents in this too(although there are also a lot of shit parents), but the general idea still stands, that babies/young children need human input to learn language and basic communication skills. Your entire personality is formed in your early formative years, and that's heavily dictated how you were raised, what kind of body and facial expressions you acquired via the people around you, as well as language. I don't think it'll be so easy for AIs to replace mothers and other people who raise young children. I wasn't referring specifically to the work itself, just the importance of the human interaction.
