I think the rumor is that they will switch to a "hole punch" for the camera when the OLED models are out (late 2026 for MBP, later for MBA). Sort of like you see on some Android phones, just a circular black cut-out at the top for the camera. So it would be less obtrusive, but still a visible camera obstruction up there.
Not sure what the other option is? I don't think Apple would going back to just having a thicker "bezel" up at the top of the screen so that you don't have to have a notch. Moving the menu bar up into the bezel area gives more usable screen space.
You can hide the notch by just switching the desktop to a 16:10 desktop resolution. (You will have to use a third-party tool for this; I use BetterDisplay for it when I want to run a full-screen game that doesn't know to display below the notch.) The menu bar will move down, leaving black space at the top.
