Amazon's recent Watch Party announcement sheds light on what the future holds for digital content consumption. It's primitive, yes, but a step in the right direction.
To summarize, Watch Party lets two people watch a movie together even though they're not in the same location. The first version limits interactions to texts and emojis but you can bet a future version will support video on both ends so you can make faces and feel closer together.
With Alexa (and Prime) Amazon has built an incredible platform for on-demand content which can be simultaneously enjoyed by multiple people regardless of location. Podcasts are a great example. There have been a number of times when I wanted to listen to one with my wife when I was probably driving home but she wasn't in the car with me. Today I'm forced to stop and wait till we're together.
In the future imagine using nothing but voice commands to tell the podcast to pause, see if my wife wants to join me, then play it for both of us to enjoy remotely. Now a channel is open for us to listen, pause, comment to each other, etc., as if we're both listening in my car.
Take it a step further and think about longer-form learning. What if two or three people want to take a course together, listening and/or watching, over an Alexa-powered Zoom-like communication platform where, again, pausing, commenting, etc., is all enabled via audio commands. Thanks to a powerful search on the back side of this you're always able to pause and ask for a deeper dive on any topic that comes up.
I realize a great deal of the learning process takes place in solitude. That means textbooks don't necessarily go away but voice UI and synchronized platforms like Watch Party will undoubtedly lead to new options for learning as well as entertainment.
