I have two kids. You should see how they use Alexa. A ton.
Like we adopted technology in ways the generation before us could never imagine, so will the next. Never forget that we have decades of bias cooked into our souls; the mouse and keyboard being the primary instruments of UI and email being the main method of communication.
The next generation has no guarantee of using the same tools we did... and in fact is very likely to be using something entirely different that seems unproductive to us.
