Are they the end-game? Room temperature was reached last year at 260 GPa, and now people are working hard to lower the pressures required.

See here for example https://www.google.com/amp/s/www.sciencenews.org/article/superconductor-room-temperature-pressure-physics-electricity/amp, it seems like 20 GPa is the new low.

Will they reach the end or will it be just another disillusionment like cuprates? Discuss.
