I don't know who manufactures them, but Meta has had a team of optics engineers working on new lenses for years.

Timewarp was one of many improvements, done by many different people over the years.

Are you referring to the classic Valve room demo which used fiducials plastered on the wall for tracking, or the Valve lighthouse which projects lasers on the walls for tracking?

Whether you put fiducials on the wall and a camera on the headset, or vice-versa (like the original Rift did) is not that relevant of a distinction. Whatever "inside out tracking" meant in 2012, today it means you get 6dof without having to setup a pile of gear in your room.
