The Systems view of technology is a prescriptive, passive view of technology. Good technology tells us what to do to get a job done. Convenience, efficiency, and volume of output are good. They are recipes or instruction manuals. The Tools view of technology is a descriptive, intentional view of technology. Autonomy, user freedom, and the ability of its users to change and customize are good. They allow craftsmanship. Good technology must be wielded by its user and their input reflected in the output, they are instruments.
Systems seek to create predictable outcomes from button presses. Tools seek to combine humanity with utility. Their output should be a reflection of the humans who use them.
