To provide some historical context for this meme, the Xbox One had recently been unveiled and at the time was going to have a mandatory Kinect. It was rumored that the camera would be un-disableable and on at all times.
EDIT: The Kinnect had a microphone in it too
Split screen multiplayer evaporated for many reasons. Besides business it's also technology.
I'm not sure you'll find a single indie split screen multiplayer game that uses a modern, queued graphics pipeline (Unity HDRP or Unreal 4+). Even among big commercial games, Fortnite notably supports 2 player split screen, but Rocket League, Borderlands and Gears of War are all Unreal 3 I think.
I think it’s more that split screen is almost exclusively the domain of ‘party’ games these days.
Then you'll love this project. The Holographic demo supports the Looking Glass display and I'm pretty sure natively supports the Kinect Azure but also works with a webcam.
