One thing about graphene, such as for a bulletproof vest. It may prevent entry of a bullet, but it does nothing to dissipate energy. A .44 mag round impact anywhere near the heart will induce cardiac infarction unless scientifically designed padding spreads the energy over a wide area. Very useful is the study of the US Navy and torpedo protection...the best way to prevent torpedo damage was to clad the hull with water filled blisters with relief valves. A solid hit on a battleship's armored belt prevented penetration but the shock transmitted caused propeller shaft misalignment, broken electrical components, and dozens of hatch closure failures.

Every game changer needs to be taken with a grain of salt.
