Yes, the market for NN based products is still in its infancy. It can explode if Apple or Samsung decide to do image or voice processing locally on a smartphone, by using a coprocessor/accelerator chip alongside with CPU/GPU. It could make sense considering the expense (power, time, bandwidth costs) of sending every image off to a datacenter for processing.

I'm curious, have you considered using analog weights (e.g. floating gate transistors, or DRAM capacitors)? This could reduce multiplication from 32 transistors to just one!
