Self limitation for safety
From apm

If objects are made form specialized gemstone based metamaterials rather than utility fog then they fundamentally can't be hacked to do direct malicious surprise attacks. Just a self suggesting example here.
Against software hacking:
- Usage of specialised and in function limited metamaterials instead of general purpouse utility fog (e.g. shelving systems).
Against direct physical hacking attacks:
- Combination lock stones as a safety measure against malicious disassebly attacks are metioned here.
- Integrated oszillators as physical timer to artificially slow down the disassembly of microcomponents - this allows for more response time.
