@glyph I have never worried about the #Singularity because in the late nineties, on two separate occasions, I spoke at length with two (then and still today) fairly well-known Ayatollahs of the movement.
They both made certain to mention that they thought I was smart—perhaps even approaching as smart as they thought they were!—and so they were candid and enthusiastic with me. Neither had studied biology (ahem ahem obviously), and both genuinely were eager to share ideas with a PhD student in molecular biology.
When I pointed out that exponential growth always, but always, leads to system collapse in nature; when I pointed out that in a universe finite in space and time, this is the rigidly necessary requirement of arithmetic, they both responded nonverbally: with a dismissive wave of the hand.
In short, the entire movement is based on the belief that Technology is Magic.
At the time I had not reached the level of cynicism to see where it would go in thirty years.
