Good passthrough is very much not indistinguishable from reality. That's why on my face there is currently a set of lightweight lenses instead of screen with a camera attached to it.
In fairness, you're not alone in being wrong about the issues with the VR business being about incremental hardware upgrades. That's a very costly mistake that a lot of very smart people have made.
But they're wrong.
It's not about the quality of the hardware or missing improvements to the features. The mode of usage, the application itself, is simply not a go-to, first-use thing. You're NEVER going to use a headset instead of a monitor. The quality of the headset doesn't matter. It's just not a leading application or a leading solution to the problem of having a display.
So no, Apple Vision Pro will not fix this problem. If I had to guess, they are aware enough of this to charge a ridiculous amount for it and see what happens before betting the farm on it like Meta did. And my guess is the takeaway will be that their branding goes a long way but people who do buy it still won't use it as their daily driver for eight hours a day of work.
That sunk cost fallacy right there is how Meta bled money on this until it was untenable to keep it up. Those goalposts have been moving for a decade now. First it was when the shipping version of the Rift got out, then when the lag got better, then when inside-out tracking was solved, then when resolution got better, then when the price was right, then when passthrough improved...
...it's none of those. It's the fact that you're in VR.
Being in VR is the dealbreaker for VR as mobile phone-like quantum leap in consumer electronics, which is what Meta thought they had.
It's not. It's a cool bit of tech with a gimmick that you crack out at parties sometimes. Or, you know, for weird porn if you live alone. I'm not judging.
That's a fine thing to be, but you need to spec your product to that target.
