You don't need to give me lessons in photography. I remember around the time of D750 Sony upgraded their sensor manufacturing process from some ancient 100-200nm or so to something newer which improved night performance tenfold. Quantum efficiency got substantially better on a better process. Nobody is telling you to shrink pixels to get 1000MPx, instead about making a better 30MPx sensor of the same size. Yet they aren't using the latest (2-5nm) processes for sensors as at their sizes that would be too expensive (I guess H100 chip-level prices for a medium-format sensor).
