I think AF could be an answer for loneliness especially for older people who may not be able to get out so much. With the way technology is moving on I think they will be able to hold ‘real’ conversations, play games, remind people to eat/drink/take medication etc.
Not sure, would depend on the functionality of the robot.
I think AF can offer relief from loneliness, but it would be down to the individual user whether this felt meaningful. But the same could be said for human interaction; if it fulfills our needs then it is a relief. But if it doesn’t it can emphasise the loneliness.
