I still dispute that eye tracked selection will prove to be the correct solution. I think it might be part of the correct solution but eye, hand and controller based interactions all have distinct advantages and disadvantages and I'm very sceptical of anyone claiming that only one of them should be the only option across a wide range of applications.

Personally speaking I have used all three and if someone put a gun to my head and insisted that I had to pick just one, it would be 6DOF controllers. (and that's me also trying to take into account future improvements in implementations for each)

I agree. I do think eye tracking selection is part of the solution, but combined with at least one physical button on a physical controller. The worst part of my Vision Pro demo was the finger gesture tracking; it's simultaneously impressively good and not nearly good enough. The reliability and tactile feedback of buttons can't be beat.

But there are a lot of ways to do minimal controllers that don't look like gamepads. They could be tiny to fit on your keychain, or built into a ring the size of a normal wedding band. You really only need one solitary button when combined with eye tracking. Since you're already carrying your phone everywhere, perhaps phones could add a physical button on the back for this use case. (The existing buttons wouldn't be good for this because they are intentionally hard to press.)

I love controllers, personally. I think the actual solution is a lot closer to making controllers into hands than the other way around. For now, though? People are going to incessantly bask in the Sony-Apple approach.

I want a little track nub like thinkpads have that’s glued to my thumb so I can click as if doing a bomb detonation movement or do basic 2D movement inputs

What about that track pad you use with your tongue? [1]

Or maybe some wires implanted into your tongue nerves that activate cursor movement when you think about moving your tongue and shock your throat muscles when you become apneic at night (a la inspire device).
