His practical business solution to it is quite sensible and likely overlooked: "Matt also believes that Canon could have designed the camera to dump the heat toward the bottom of the camera and then sold a separate base attachment for videographers that provides vastly extended recording times."
In the video he more specifically describes how it could be possible to use the mounting point's metal base to transmit heat to a mounted cooling attachment.
