Aeon Magazine has a longish article about sexbots, robots designed for sex with humans. This article deals with relatively weird stuff, which it treats seriously, even clinically. Hat tip to RealClearScience for the link.
Apparently a sexbot exists now ... who knew? ... brand named Roxxxy. Roxxxy can assume various "personalities" depending on the customer's choice. The nerds on Big Bang Theory need one of these.
