Why this is presented as bullshit insane I have no idea. It seems like an amazingly brilliant solution to me, much better than the 'engineering' solution suggested where your vision flashes black every time you move your eyes. Also worth mentioning this weirdness is repeated in human consciousness all the time. Like the theory (tested as far as we can) that tall people perceiving the world further in the past so they can reconsile nerve impulses from their feet as happening at the same time as visual stimulus. We've known about phenomenon like this for a long time as well as other deeper revelations like, what is sometimes called, the illusion of free will. And yet we constantly act surprised that our conscious experience of the world doesn't correlate to what we find out is 'actually' happening.
So we are flawed meat bags with insane, non sensical brain mechanics, if only our biological solutions were as well thought out as VR eh?
How glad am I that the incredible complexity and subtly of evolution created my visual system and not Valve or Sony.
