Agreed, but that doesn't solve either the chair problem or the

panning or multiple cameras and switching, either of which
require human attention.
John, we are in 2015. Computer vision can definitely help tracking the speaker.
You can find face tracking algorithms in many packages, including open source
variants. Computer systems can easily track the speaker's face, crop the image
around that, and send the speaker-focused image over the video. This is not
rocket science. The pink box is obsolete.
