Scanners are also a tech that has pretty much plateaued - correct me if I am wrong, but the linear arrays are fairly cheap and the resolution is a product of the linear array and the minimum step size, and steppers have not gotten much better. There are 2x+ more dense linear arrays than the v600 has that exist, but that only would improve one dimension of the resolution.

Also, the v600 is a great consumer scanner, but OH BOY can you get more fancy, for film you have the hasselblad/imacon line that are still a few thousand used, then you have drum scanners for the highest possible film scanning quality. For a more direct v600 comparison, there is this really, really old scanner that outperforms it: https://www.scansolutionsonline.com/media/1168/cezanne-elite...

A more modern flatbed scanner: https://epson.com/For-Work/Scanners/Photo-and-Graphics/Epson... Sadly lower res than what used to be out there.
