Well, in a way, they're right. You could consider the printing press, or the aeroplane, or electricity, or the telegraph, to be a mini-"singularity" event since it drastically changed the world in ways unpredictable beforehand. "Singularity" doesn't necessarily equate to "rapture of the nerds where AI gods make everything awesome (and/or kill us all)", it just means "point where things get weird and we can't predict what will happen next."
