The probability seems quite high. Anyone can google the dancing bot built by Jordan Wolfson in the US, the robot replica of Scarlett Johanssen built by Hong Kong's Ricky Ma, China's Jia Jia robot, and Japan's Project Aiko, and see where this is going.
Well, last week my closest male friend (whom I've known for over 30 years) dropped a bomb on me when he said he wants to not only build what he calls a "love-bot", but he wants to actually crowdfund mass production of it. I admit this is partly my fault, because he knows I have over 20 years' experience in working with metal alloys and silicone rubber mix, and a couple of years ago I wrote a story which flopped but not before my friend could read it and develop a major crush on its female main character. He has over 20 years' experience in computer programming and knows it would be possible to develop a bot that could walk, talk, see, hear, eat, drink, cry... and possibly LOVE. Believe me I know the technology already exists to pull this off. David Levy, author of Love And Sex With Robots, says this will happen by 2050. I think it will happen a lot sooner than that.
I can only speak for myself when I say a "love-bot" would be just the thing for me when I want a little stimulating conversation or a woman I can hug and take out to dinner... my buddy has been through a very nasty divorce and it seems to me he wants to do this to get back at his ex. He is great at analyzing details but he often fails to see the big picture. I think he doesn't understand how very disruptive it would be if it indeed became possible to plunk down a couple thousand bucks, select a bot from a catalog, and a week later she arrives at your house.
Women probably wouldn't appreciate getting dumped for a machine. Men who want to become biological dads would have no use for a bot either. But regardless of whether my buddy eventually comes to his senses or not, the genie is already out of the bottle, and the law of supply and demand will take over. An article in the Daily Mail from last April says that 26% of men, when asked, said they'd date a robot (the response from women was not recorded).
Remember before the 2016 election, how some of us thought Trump didn't have a snowball's chance in hell of winning the election, and we were complacent enough to laugh about it? Then he won and the initial reaction was shock, followed by an almost fatalistic negativity when we relized we'll have to put up with him for the next 4 years. I predict somethng similar will happen when the bot revolution gets underway.
