That's a nice model that gives some interesting numbers, but I would tend
to disagree that human-brain computing parity will be required. Consider,
for a moment: the cerebellum, the motor cortices, the limbic system, all
of which contain billions of neurons which are used in most estimations of
the "power" of the human brain, but which are almost completely irrelevant
for abstract design tasks.
Assuming that artificial design engineers will not require processing
power necessary for motor control, proprioception, audio or perhaps even
visual processing, I believe it would be safe to say that many teraflops
can be shaved off the computational capacity neccessary for complex design
tasks such as self-reengineering. It would not be unreasonable to move
that time window up by several years.
