I think that the poster in question was assuming that you were unfamiliar with the Singularity in general, rather than enquiring as to the nature of the Singularity that occurred in-comic in particular.

Or, possibly, that you were silly enough to confuse the QC world with our own; they've had Strong AI since the start of the comic, after all, a superhero who delivers pizzas, and one one the cast grew up on a space station. Needless to say, it only appears similar to ours since we're just seeing the lives of a small circle of hipsters who run a coffee shop and an office-bitch-turned-librarian. I'd imagine that, say, their US Military probably looks quite different to ours.
