The hand tracking has seen continuous improvement and the depth correct passthrough is pretty good and I'm sure quite a feat to accomplish.

Its worth noting that much of that 10 Billion wasn't just spent on Horizon Worlds as critics off-handedly suggest, but has been sunk in to lots of acquisitions (hardware and software companies) and research, much of which has yet to be seen in released products.

I'm very impressed with the ambition of what they are trying to do and their committment to a longer term vision which is something that often is lacking in many companies. As an example Nvidia were working on AI tooling and hardware for a decade before it really started to pay off big.
