I think lonely people crave companionship more than sex - given the choice. Society has formed in a way where "beautiful people" tend to get the breaks, get the sex and generally have a better quality of life. I understand a big part of this is also down to evolution and reproduction, but we have entire industries built on sexual aspiration such as fashion, advertising and porn.
I understand people crave sexual gratification, that's human nature, but I think products like this will only serve to compound the problem, make more people who feel this way look inward and ultimately more unfulfilled and lonely.
Would research and technology not be better served if it was used to help break these barriers and bring people together - rather than isolate them in their own lonely existences.
I am aware a lot of this is my own opnion, I just think it's pretty disgusting that this could be a possible future.
