> in the real world, no not everything is in focus all of the time. i'm currently sitting 38" away from the wall, my monitor is 8" from the wall. If I'm focused on the monitor, the objects hanging on the wall are not in focus.

But that is also the case in VR so I’m not sure why one would consider “everything to be in focus” which is what my question is getting at (why do people say that). If I focus on something in VR the objects behind it will also go out of focus. Unlike in cinema where a camera has to choose what is in focus, in VR our eyes choose what to focus on just like in the real world.
