If you can scale, you can deliver at any level of abstraction.

“HCI has had a massive impact on the world through streamlining and enabling millions of interfaces on billions of devices. As we face the potential of a tenfold increase in the number of devices and their complexity, it is worth asking about the relationship between HCI and scale. Do the tools and research methods we currently deploy scale to the millions of future interfaces and systems, used by billions of people, across multiple contexts? In this article we outline how we see the challenge of scale. By scale we mean how technology is used in large networks of interconnected systems, with billions of users, across diverse contexts. How can we understand and design for this complex of interconnected uses? Put simply, does HCI scale?”
