Human scale tools
Strive to build tools at human scale.
If a system is to serve the creative spirit, it must be entirely comprehensible to a single individual.
The point here is that the human potential manifests itself in individuals. To realize this potential, we must provide a medium that can be mastered by a single individual. Any barrier that exists between the user and some part of the system will eventually be a barrier to creative expression.
— Alan Kay
