MEMS is already in the Military... Hmmm ethics could go out the window if you start seeing $Billions flashed at your face....
As the paragraph states...

But even MEMS is undergoing technology enhancements. Current MEMS IMUs can drift up to 100 degrees off target each hour, which is not a problem for ERGM or LRLAP, which are only in the air a few minutes, but for longer ranges that much drift would be disastrous. The government wants to get the MEMS IMU down to 1 degree per hour drift — equivalent to the ring laser and FOG (fiber optic guided) gyros — for the smaller long-range systems. However, achieving that level of accuracy requires a host of technology applications, from trimming the silicon to physics on the surface of a silicon substrate and what materials are added to it — all the intricacies of the lithography equipment that makes silicon chips.
"A MEMS IMU operates by measuring nanoscopic vibrations on a piece of silicon and the related changes of frequency. If you increase velocity by one mile per hour, how much deflection actually happens at the subatomic level and does it happen all the time. If the structure is bigger or smaller is it better or worse? As we make things smaller and smaller and smaller, the effects of physics are much more impacting on our ability to determine and control and measure the vibrations and changes in frequency," Grace says.
