In A Brief Rant on the Future of Interaction Design, the author describes the superiority of physical interactions over digital interactions. However, the author seems to have reduced digital interactions to just screens and there other modes of interactivity out in the world like displayed in the following video: 

However, despite this fallacy I understand why the author talks about screens specifically. She does so because it is the predominant mode of interaction at this age. I think this is true because, it has become very easy for web developers and software engineers to build things that can be used in this interface. People who do not necessarily understand  the systematic components of a tablet or a computer,can materialize their products as long as they are literate in NodeJS and ReactJS.

For example, the device in the above video is not easily programmable, I will probably have to understand the lingo and the intricacy of the hardware components and then try to build it. So you do not really see David down the road playing ping pong with it. 

On the other hand,  screen technology has empowered so many people to build new software technologies and as a result has become more accessible. It is clear why it is prevalent . At the same time I understand that the author is trying communicate the unfortunate trade-off between empowering the production of new software and exploring and appreciating different modes of interactivity.
