The ability of robotic sex dolls to physically and emotionally imitate real people (often idealized and overly sexual women) to provide a satisfying and intimate experience is a significant innovation. Yes, it is an important risk factor.
For example, developers looking to improve the user experience of sex robots can create machine learning algorithms to increase trust between human users and robots. Trust certainly benefits from intimacy. However, once developed, this technology can be used in sex robots and other forms to instill trust even if it is probably against the interests of the user.
