Parallelism changes absolutely nothing other than speed of execution.
Strong AI is refuted because syntax is insufficient for semantics. Allowing the syntax to execute in parallel will not alter this because the refutation of strong AI attacks the logical basis for the strong AI hypothesis itself. If you are trying to build a television with tinker-toys it does not improve your chances to substitute higher quality tinker-toys for the older wooden ones. You will still never get a functional TV.
They do not actually have a physical non-von Neumann architecture. They are simulating a brain on simulated neurosynaptic cores on a simulated non-von Neumann architecture on a Blue Gene/Q super computer which consists of 64-bit PowerPC A2 processors connected in a toroidal network. No wonder it's slow.
They are trying to reach "True North" and believe they are headed in the right direction but they do not know if the Compass they have built actually measures what they believe it measures. Nor do they know if once they get there True North will do what they want it to do. They do not even know how what they want to do does what it does but they believe if they use faster computers that will overcome their lack of knowledge of how actual minds arise out of actual brains, which they don't know how they are constructed. Nor do they know how the actual neurons of which actual brains are constructed actually function in real life.
But they're published. So... you know... there's that.
If you cannot simulate round worms, do not know how neurons actually work and do not even know how memories are stored in natural brains you are in no danger of building Colossus.
People are highly susceptible to magical thinking. When the telegraph was invented people thought the mind was like the telegraph because...... magic is why. Building more and faster wires and better telegraph stations and connecting them in advanced topologies will not change the fact that you are living in a fantasy world.
Strong AI is refuted because syntax is insufficient for semantics.
A wild Aristotelian Teleologist appears!
Phrasing claims in the passive voice to lend an air of authority is grating to the educated ear.
Aside from stylistic concerns, though, I believe you're claiming that electronic circuits don't really mean anything. However, I'm not sure whether you're making the testable claim that no arrangement of electronic circuits will ever perform complicated cross-domain optimization better than a human, or the untestable claim that no electronic circuit will ever really be able to think.

Here is the research report from IBM, with the simple title "10^14":

It's nothing like a real brain simulation, of course, but illustrates that hardware to do this is getting very close.
There is likely to be quite a long overhang between the hardware and the software...
