The future is here. Robots have, under our noses, become more advanced and complex, with some - albeit still rare and prohibitively expensive - able to be indistinguishable from humans. The fears over such things, while initially driven by panic and uncertainty, have passed and it was long since decided that for the sake of society's collective comfort, hiding the roles AI play was of paramount importance.
In this, they largely succeeded, but if you look closely, you can still spot them. They want to be noticed. They want to be seen.
Pick something you might use in your daily life - a vending machine, a coffee maker, your very own toilet - and allow the AI inhabiting it to shine through, allowing elements of its unique personality to pierce our protective veil of ignorance. Just don't be too obvious - there's a fine line between standing out a little and inciting panic, and no robot would want to risk decommissioning and disposal.
