Imagine you're sitting in restaurant waiting for the waiter while doing some work on your Vision Pro. The waiter shows up and says 'sir...'. You look at him and... there were two options:

it's just a black screen so it's not clear if you're actually looking at him. Are you paying attention? Of are you still 'inside' and can't hear/see anyone
you have this fake eyes indicating that you're actually looking at him

It's a really stupid "solution" to a huge problem all VR/AR has The actual solution? Don't buy it.
