I think he was stating that "can't be worse" was a requirement, not a fact. As in, it _must not_ be worse than existing options ($1000 in monitors), ie: resolution, as easy to do everything you already do, etc.
That's on purpose. Resolution is nothing in VR, reaction time is everything. You only need a very wide field, like 800x200px. This would be luxury VR glasses.
However for other, more non-immersive applications, like AR resolution became more important. Which leads go slower reaction times. Which can lead to sickness and lawsuits.
Yes it can. The resolution of AR/VR glasses is less than my iPhone or my laptop monitor.
Now you’re telling me that plugging in a big bulky headset is somehow going to deliver a not worse experience than thee other devices that don’t require an unparalleled level of immersion (both a pro and a con) yet able to show less detail?
