100%. There's a reason there aren't other standalone sets this good or better. It's very, very hard. The tech just isn't there to do a lot better than this without the price being even more insane. I'm really curious to see how the tech progresses. Some of the hurdles are incredibly complex.
This is one of the crazier teardown videos I've ever seen for any device. It's just jam packed with stuff. The engineering involved is ridiculous, regardless of what you think about the device's validity or of Apple.
And IIRC those are all PCVR sets and not standalone.
