### Yes, I know. But their plan could lead to a deceleration system.

### The self-guided bullets I wrote about do have electronics. Why would
mass be an issue for robustness under acceleration? We are talking about
micron-thin objects. They tend to stand up to acceleration well. Why would
the duration of acceleration matter for solid-state objects?
