operate the machine
Consider these planes (an ancient tool): their designers sought fitness for use, ease of use, good control, long-lasting materials, a good feel in the hand, efficiency of operation, precise adjustment. In use over time, these tools come to be loved by their owners.

Most of the qualities we seek in a machine have been valued through the ages.
• useful
• usable
• desirable
• affordable for the right people
• appropriately complex
• appropriately styled
• appropriately adaptable, extensible, malleable
• overall, having “good fit” with people, context, activity, result

An athletic woman in colorful clothing runs into the auditorium, carrying a huge hammer…
…which she throws into the screen, smashing the image and voice of the status quo.
hello.
