Back in the day we used to refer to our electronic devices as PDAs — Personal Digital Assistants. They weren’t. In fact, they weren’t much more than battery-operated day planners, the paper versions of which were in style around the turn of the century.
Today these devices have given way to Internet-connected smartphones that are finally starting to include the ability to complete core tasks via voice-assisted input. Apple has Siri. Google has Google Now. Finally, Microsoft has Cortana.
