To discuss this question, we need to know what is sex robots first, they are real different to some blow-up doll that doesn’t talk, of course have some different with tpe sex doll, although these tpe love dolls are with hyper realistic details and most realistic touch feel, but if they can’t talk and walk, and without artificial intelligence, still can’t said is a real sex robot.
Know what is a real sex robot, you may understand to some extent why people are so expecting sex robots.
First, sex robots can satisfying different sexual needs of different persons. Sex robots can be said to be the upgraded versions of the common tpe silicone sex dolls. The commonality between the two(sex robots and common sex doll) is(Take UXDOLL dolls as an example), they with the most realistic human like details and hyper real skin touch feel, smooth and soft, with strong alloy skeleton and flexible joints, this let they can pose many different postures as a real women, the different is sex robots can do more refined actions, to present different facial expressions according to the dialogue, such as smile, or sad.
Of course, compare to those traditional tpe sex dolls that designed for satisfy different persons sexual needs, sex robots still have many benefits.
Second, except for satisfying sexual needs, sex robots also can communicate with people, talk, chat, and respond to you like a real person, not just satisfying sexual needs, this means more in some sides.
Third, Compare to human-human relationships, there still many guys preferred to spend time on his computer rather than with real girls, and computers usually can bring some guys wonder experience in some way. They think to keep relationship with a real girl is a little trouble and waste of time. Need to go shopping with her, listen to her whining, and also always ready to deal with her temper. Obviously, sex robots can built a special and simple interactive relationship with you instead of boring relationship with tpe silicone sex dolls, or complex relationship with real women/girls.
Sex robots can let you feel like is chat with a real women, she can remember what you are like or hate if you willing to tell her, according to your facial expressions, she can detect whether you are happy or not, then she will know how to do to help or talk to you. That may the point why people are so expected to the sex robots.
