There's no question in my mind that the evolution of Apple's Siri and Google Assistant will include mood and emotion detection capabilities.

Mood and emotion detection is a new frontier in human-machine interaction. It will make our computers and phones both more capable and more "human."

It will also help advertisers target us more effectively.

How do you feel about this? If you're not sure, don't worry. Soon, your phone will be able to tell you.
