Or another example: 8 years ago I spent $320 on a 1080p 27" (massive pixels) monitor with horrible color reproduction and contrast. 4 years ago I upgraded to a new monitor and for $300 I was able to get 4k 27" with >100% sRGB.

And when you consider inflation, progress is even greater.

It's the same with GPUs, and to a lesser extent CPUs and memory and storage. Moores law is great in many ways, but as a buyer of high end technology it always stings to see the same thing be 30-50% cheaper a few years later.

Progress does seem to have slowed down within the past few years for monitors. I expect the pandemic is relevant there.
