As much as I'm a regular xkcd reader, I'm mildly annoyed with this strip, because I imagine lots of people will be exposed to the idea of the AI-box experiment for the first time through it, and they'll get this exposure together with an unimportant, extremely speculative idea that they're helpfully informed you're meant to make fun of. Like, why even bring the basilisk up? What % of xkcd readers will even know what it is?

If the strip was also clever or funny, I'd see the point, but as it's not, I don't.
