All it says is predicting the future is incredibly hard and all predictions (the ones predicting success as well as failure) are without much weight.
I wrote about some of these input factors in my post on category defining products a few years back: https://nickpunt.com/blog/category-defining-products/
Personally, I feel Vision is a bit too broadly scoped for a v1. 3d photos really didn't need to be in there. The consumer use cases that Apple loves really aren't where Vision is providing next level value add, whereas the remote workplace ones are. But I understand those alone are not enough to drive adoption so I can see why they wanted to make it more consumer oriented.
My hunch is they pivot slightly toward workplace in subsequent versions, much like they did with Apple Watch pivoting toward health and away from luxury.
This applies to Apple just as to every other company. It's not like Apple hasn't had product failures, after all.
