Almost everyone will have a smart watch in the future for security and health reasons.

Parents will be able to know where their kids are at all times. Someone being attacked could shout into their watch that they need 911 and the GPS will route help to the scene. Health monitoring will become much more sophisticated. Women will enjoy going out without worrying about putting a phone in a pocket that doesn't exist. The heating and cooling of your car, office, and home will adjust to your body's temperature. Society will go cashless.

The biggest potential in smartwatches doesn't depend much on the screen interaction.
