@jgordon that was a good summary of competing factors. The original concept of The Singularity hinges on superhuman intelligence. Now we face the possibility of a lesser singularity supported by lesser intelligences (human and machine).

I linked earlier to an options trading experiment in which voting by fallible AIs made possible a "don't know" output. Not only that, a "do nothing" signal.

Things like that might allow progress without excess risk.
