I would guess the plan is to have the foundational machine vision tech that becomes the core of robotics sensors. Not just Optimus but every robot arm in a factory, robot mule, etc. I don't think everything will have LIDAR if its proven to be unnecessary.

The foundational tech Tesla is using is the same as everyone.

We know this because there have been public presentations about it.

And inventing groundbreaking new tech is so far the domain of academia and large, well funded R&D labs. And almost always shared.
