Futurama, Season 6, Episode 15: Benderama

Naturally, this episode's goal is entertainment, not so much the accurate portrayal of the technology.

The premise of "Benderama" is based around the transhumanist theory of grey goo, an end-of-the-world scenario in which out-of-control self-replicating robots consume all matter on Earth while building more of themselves.

The episode is not officially available for viewing online (but you can still find it, of course).

Apropos the Wikipedia article, in what way is grey goo a "transhumanist theory"?

Grey goo scenarios are relatively straightforward extrapolations of mundane technological progress and complex system dynamics with analogues in real biological systems. Subscribing to transhumanism is not a prerequisite to thinking that grey goo is a plausible region of the technological development phase space.
