the blogger closed discussion before I could reply so I'll reply on here for what good it does me.

Whether a technological singularity is desirable is debatable. Whether development of human-equivalent AI would lead to technological singularity is debatable. On the other hand, human-equivalent AI seems inevitable to me. Author asserts some things without much in the way of proof:

"You could take a precise reading of the structure of the human's brain and simulate that brain inside a computer. But taking this initial reading is impossible in practice right now, and may remain so indefinitely, and computers need to be, conservatively, ten orders of magnitude more powerful before the simulation step becomes possible."

Why would this remain impossible in practice indefinitely? It's only a matter of time and effort until the human brain's goings-on can be reproduced outside a human brain, no matter how many orders of magnitude "more powerful" thee equipment needs to be. Unless there is truly some human-inaccessible spiritual process that goes on alongside physical processes in the human brain to produce human intelligence, there's no reason purely physical processes can't be reproduced outside a human brain.
