I'm not sure whatever for they need such nanowire synapses, because in real/wet neural networks the timings of neural firing, delay and latency is as essential as the synapse itself. How fast a wet synapse works is modulated, some are isolated from modulation. I don't think a new synthetic synapse being 30.000x faster will do anything good if the whole system is not up to par with a wet neural system.
