Soon enough social apps will use your selfie cam to track your eyes. Ads will only play when your eyes are engaged and pause if you're not looking at the screen. Oh boy.
Same with TVs, the built in camera will see who's watching, and Netflix, etc, will stop streaming when it sees 5 people watching when your account is only set for 4. Either one person leaves the room or you upgrade to continue watching.
Have you never seen a movie set in space? Evrytime someone gets sucked into space they freeze. You saying every movie got it wrong?? Space is cold. Duh.
