From the sounds of it, they made the most advanced headset on the market by a big margin. The problem is that doesn't matter if no one is able to get it.
Microsoft made the same mistake with the Hololens. At the time it was the most advenced headset and was just as cutting edge as this Apple joint is now, and it went nowhere because nobody at that time was going to spend 1000+ on a AR/VR headset.
These developers don't seem to understand that VR/AR is still in a proving phase. A lot of people understand it, but a lot more people don't really get why it's something worth investing it. They're trying to treat this shit like the iPhone and don't seem to understand that the strategy works for phones because people already have them integrated into their everyday lives and don't need to be sold on them.
