Ah, those brains in vats. Always showing up in epistemology, taking the 
jobs from us honest Boltzmann brains.

I like the paper. It actually gives a good reason not to believe in 
weird existential risk theories (maybe the LHC makes black holes when it 
is cooled too much? And somebody speaks Swiss-German nearby? And that 
person is red-haired?) since such theories also predict a too wide range 
of phenomena (if temperature, language and haircolor matters for 
particle experiments, we ought to see a lot of random things when we do 
them rather than consistent physics up to 20 TeV and then *bang* when Dr 
Rothaarig shows up.)
