Illich argued that we will never be an effective society until we take back control over tools and institutions that negate our own natural abilities. Illich believed that tools are intrinsic to social relationships. They should not enforce power and compulsion, but rather encourage participation, trust and sociability: “Convivial tools are those which give each person who uses them the greatest opportunity to enrich the environment with the fruits of his or her vision. Industrial tools deny this possibility to those who use them, and they allow their designers to determine the meaning and expectations of others.”

Ivan Illich is a famous and savage critic of industrial society. I am in total agreement with many of [his] wider arguments.
