Standards are good, but not until you get to the point where new things are not being made.

Intesterestingly, a standardation does not imply that the technology will not change/improve or progress. Take the movie camera as an example, it has improved greatly since the 1930s when the standardization occured.

If so where do we stop?

It will probably will probably never stop but I believe it will converge. This is the "perceptual threshold" I refer to.
