> I've used VR headsets, nothing is comfortable after even an hour of use, we're just not designed for that
There seems to be something specific about VR that invites people to vastly over-extrapolate their personal experience. I find it really difficult to believe you've tried the Quest Pro or NReal Air [0].
Current hardware have lots of other flaws but what you mention (comfort) is mostly solved for most people (there are always exceptions).
