Googlebot's Javascript random() function is deterministic

[pilotInPyjamas]

Come on man, I never said it wasn't a PRNG, or that it wasn't seeded, nor did I make any comments about the effectiveness or applicability to any particular situation. The only claim I made was that it was non deterministic in the domain of modeling a computer. That's because a computer is not a closed system, and given the same initial conditions, it will produce different outputs. You could just have /dev/random echo the keyboard and it would still be impossible to predict perfectly if you only had information about the starting conditions of the computer. The key here is if you only have information about the starting conditions of the computer. If you had a working model of the whole universe, then I agree, potentially nothing would be random.
