In computer vision transformers have basically taken over most perception fields. If you look at paperswithcode benchmarks it’s common to find like 10/10 recent winners being transformer based against common CV problems. Note, I’m not talking about VLMs here, just small ViTs with a few million parameters. YOLOs and other CNNs are still hanging around for detection but it’s only a matter of time.

I do some sim racing. I can race for hours with a Reverb G2 but get nauseous within minutes with a Meta Quest Pro.

From my perspective:

1. Eye tracking for interaction vs hand tracking. If the UX works out, the amount of precision that can be reached is just far higher with less effort - just seems to be an easier technical problem.

2. Resolution and lensing. Most VR headsets have fairly low quality fresnel lenses which cause distortion near the edges (basically - if you want to see something in good detail, you have to tilt your whole head to look at it), and in general the resolution is not good enough to see things that are 'far away' (those who play games like DCS have to use the 'binoculars' feature with headsets to accurately see targets). With a device like an HP Reverb, the resolution is probably close to good enough, the lensing is not - the Meta Quest Pro has a good enough lens, but not resolution. I'd expect the lensing on the Apple device to be top of market, and we know the resolution is ~2.5x more dense than the Meta Quest Pro - which should be closer to going from SD to HD TV rather than HD to 4k. Essentially, if you try to code on a Meta Quest Pro, the text looks a bit blurry. With the Vision Pro, it won't.

3. Custom face cushion + prescription lenses. Comfort is everything with these devices and nothing is worse than a headset putting pressure in the wrong places. It'll cost much more, but be totally worth it.

4. People claim common nausea when using VR. I've felt it too, but only on certain headsets. My money is other companies know what causes folks to feel bad, but have had to make technical tradeoffs which mean that nausea remains a problem. I'd put money on Apple having done serious research into 'what causes nausea when using headsets' which causes this to minimised on their headsets.

5. Software stack and usability. VR stacks are typically fairly clunky, usually Android derived, usually behaving a bit like a dodgy phone. iOS/MacOS are usually not most feature-ful, but a core usually works very very well. Will likely push bar a lot higher, change the shape of industry (e.g. samsungs are so good because of the iPhone competition).

Basically, having used some of these devices - the complaints I have with these right now, are the same things that Apple has real, technical solutions for. And the price isn't even _that_ high compared to other players in the market. Pimax Crystal is $1600 for what right now is a fairly buggy user experience. Their vapourware Pimax 12k is listed as starting at $2400 for the most basic model, though it's been in that state for well over a year.

It's also worth noting that this is dependent on model. E.g. I can handle an HP Reverb G2 indefinitely, but a Meta Quest Pro for only about 30 minutes before I feel ill.

Bullet trains are sadly not maglev. They actually don't go _that_ fast (180-200MPH-ish is common), but look incredibly sleek compared to European high speed trains due to the aerodynamics of dealing with the large number of tunnels that Japan has.
