This is about 10,000x standard pressure. CRTs operate at 0.0000001x standard pressure, for reference -- they implode.
For example if superconductivity is desired from a 1 square inch (6.5e-4 m^2) footprint of this material, a weight of 6.5e5 N must fully rest on that footprint. Near the surface of earth that translates to a mass of approximately 146,000 lbs. Something like the mass of 3 tanks.
You'll have to ask a smart guy what deposition, subtraction, injection, or teleportation process he's going to use to make a permanent diamond container that leverages the high compressive strength because I'm stupid.
