Jeez I'd love to know what Apple's R&D debt on Vision Pro is, based on current sales to date. I really really hope they continue to push for a headset that's within reach of average people but the hole must be so deep at this point I wouldn't be surprised if they cut their losses.
As Carmack pointed out the problem with AR/VR right now - it's not the hardware, it's the software. Until the "visicalc" must have killer app shows up to move the hardware, there is little incentive for general users to make the investment.
