Ars Technica: In your series, Murderbot is basically a Ken doll with no genitals. The book only mentioned that Murderbot has no interest in sex. But the question of what's under the hood, so to speak, is an obvious one that one character in particular rather obsesses over.

Chris Weitz: It's not really addressed in the book, but certainly, Murderbot, in this show as well, has absolutely no interest in romance or sex or love. This was a personable way to point it out. There was a question of, once you've got Alexander in this role, hasn't anybody noticed what it looks like? And also, the sort of exploitation that bot constructs are subjected to in this world that Martha has created meant that someone was probably going to treat it like an object at some point.

Paul Weitz: I also think, both of us having kids, you get a little more exposed to ways of thinking that imply that the way that we were brought up thinking of romance and sexuality and gender is not all there is to it and that, possibly, in the future, it's not going to be so strange, this idea that one can be either asexual or—

Chris Weitz: A-romantic. I think that Murderbot, among neurodivergent communities and a-romantic, asexual communities, it's a character that people feel they can identify with—even people who have social anxiety like myself or people who think that human beings can be annoying, which is pretty much everyone at some point or another.ALT

Good to know that the showrunners are being very deliberate in keeping Murderbot aroace, since I’ve been some people being worried they would ignore that part of the books.
