You don't think cameras will improve enough that 8k can be shot with same or even less lighting than is used today? Is it a physical limitation?

Yes it's physical. The max exposure time is inversely correlated with the framerate. If you shoot at 100fps for example you cannot keep the shutter open (and capture photons) for longer than 10ms, as you need to close and start the next frame, and it will look dark. And the standard for movies is to use 180° exposure meaning half the inverse of the framerate.
