What do optics or light have to do with Electronic View Finders (EVF)
A very major limit on how EVFs perform is how much time the camera's sensor has to capture the light that is needed to generate the image for the EVF. If you are light-limited (and, we're light limited a heck of a lot), the EVF has to wait for the sensor to integrate the light for the necessary time, and that integration is the limiting factor on both the quality and speed of the EVF.
Moore's law says, the number of transistors on integrated circuits doubles approximately every two years. Often misquoted as every 18 months I've often seen the 18 month claim in many consumer computer magazines.
Actually, that's closer than usual, but that isn't correct either. Moore's law is about economics. (Emphasis added):
"The complexity for minimum component costs
has increased at a rate of roughly a factor of two per year... Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years." -- Gordon Moore 1965
He changed the "per year" part to every two years in 1975 when the time horizon of his original prediction ended.
