I just finished watching Will Smith talking to one! I think it would of course be possible.A few things have to come into play.
Say I was very much alone, no family and just really had no one in my everyday life.
Then yes for me.
I get attached to people in commercials, it is very slight but it happens.
If asked would they be any use in the future ?
yes, there are a great deal of lonely older people. I see nothing wrong with it, the cost may be a problem but it is the same as little girls loving their dolls when young. Talking to them and hugging them, so a robot talking back would be nice for those who have no one.
I'm surprised it has taken this long, and so much money? To bring them out now.
