We are sexy, sexy Von Neumann machines.
Title text: We are sexy, sexy Von Neumann machines.

Explanation

Despite how advanced technology is, we (on late 2012) still have yet to create a machine that replicates itself, an accomplishment that only biological organisms can lay claim to.

A Von Neumann machine refers to the underlying infrastructure behind most the computers of our time. Von Neumann machines allow data and executable code to intermingle in a single memory space. By contrast the Harvard architecture, which is used in many automated voting machines, strictly separates data and executable code, which makes it much harder to exploit but is much more difficult to construct as it requires parallel structures to store code and data.

It seems to me that Cueball is examining Megan's abdomen (where her uterus, the "factory" itself, is contained), rather than her crotch as stated by the Explain XKCD description. It's not just the logic, but also the shape of Cueball's head (which may just be an artifact of the drawing process). Does anyone agree, or is it probably just me?

It's there in the official transcript.117.194.199.173 15:08, 11 February 2013 (UTC)
Still seems kind of, i don't know, incorrect. The crotch is the factory door, not the factory. 108.162.219.58 18:18, 24 January 2014 (UTC)

Hmmm, self-replicating Von Neumann machines are more like parthenogenic aphids (asexual or "clones") rather than human sexual reproduction... Meg would not be able to copy herself. Apart from that, I like this cartoon as it does point out how fantastic reproduction really is. Oh, and Cueball 'should' be looking at her abdomen rather than her crotch methinks Squirreltape (talk) 16:13, 13 February 2014 (UTC)
