  In the era where personal devices and applications are pervasive, individuals
are continuously generating and interacting with a vast amount of data. Despite
this, access to and control over such data remains challenging due to its
scattering across various app providers and formats. This paper presents
Human-Scale Computing, a vision and an approach where every individual has
straightforward, unified access to their data across all devices, apps, and
services. Key to this solution is the Human Scale Portal, a progressively
designed intermediary that integrates different applications and service
providers. This design adopts a transitional development and deployment
strategy, involving an initial bootstrapping phase to engage application
providers, an acceleration phase to enhance the convenience of access, and an
eventual solution. We believe that this progressive "narrow waist" design can
bridge the gap between the current state of data access and our envisioned
future of human-scale access.
