This 30-minute video explains the history of non-volatile RAM,
specifically 3D XPoint, Optane, and CXL, and how hard it is to
re-architect software to use it when DRAM and NAND performance continues

This is obviously relevant because databases like quick access to
non-volatile storage. In summary, the technology never hit critical
mass and is being deemphasized.
