It's only relevant as a signpost that the "intelligence explosion" version of the Singularity is starting to get cultural traction.
We could charitably interpret that as "using the same definition of 'Singularity' as the Singularity Institute, instead of Kurzweil's or some other variant" (which is correct).
I agree. My pedantic side was acting up and I was mainly focusing on the fact that the comic didn't mention FAI, which is what really sets SIAI apart from other Singularity groups/thinkers.
Look, Dinosaur Comics has a strip about the singularity. And it's pretty much in line with the Singularity Institute's views on the matter.
