As time marches on and sensor tech advances, it is the SMALLER format that will become more accepted as being good enough by a wider range of users, not the larger. At one point, 35mm WAS the smaller format. Now, we have progressed. 35 mm is the older, larger format. So where do we stand?

And what are your beliefs are based upon?

Are you familiar with quantum properties of light? The noise of the camera is in a large degree determined by light intensity and the area of the surface it is collected from. The modern sensors QE is about 50%, there isn't much improvement left in this regard. It's doesn't take a genius to understand that even ideal m4/3 sensor will not achieve SNR of the modern non-ideal FF sensors. When technology is perfected, the 4x difference in area will be the only determining factor and unbridgeable gap between these two formats.

I agree that a 35mm sensor can produce better IQ than an m4/3 size sensor. My point is that eventually, it just won't matter anymore. As technology improves, it benefits both sizes, so yes, 35mm IQ is, and will remain, superior to m4/3. But when small sensors are good enough for most people, most people will buy them.

In the same way that 35mm is superior to m4/3, medium format is superior to 35mm. Why isn't medium format the future?

Answer a simple question. If two cameras have the same size and weigh, ergonomics, cost, but one can have potentially better image quality better technical parameters, larger selection of lenses, etc., which one would you choose?

Your question is flawed because a bigger sensor will always need bigger lenses. The available stock of lenses is way bigger already, so this point is moot. I have no doubt that taking the mirror off would allow somewhat smaller FF lenses : I have been a film RF user so I know it from experience, but this is true for MFT and by contrast  is already available.
