right up until it started blinking
Relationships are going to be so sexually charged and toxic for the younger generation of the world when those things get to a lifelike stage. I imagine widespread acceptance will start when an economically priced roomba version of a lifelike person is available. Then people would be allowed to buy downloadable, and attachable "mods." I can see the news headline now "Wife breaks up with Husband when she came home and found him fucking the Roomba v3.1! Roomba says it was just cleaning up a mess!"
