Paul Pangaro

Life

Pangaro studied humanities and computer science at MIT, graduating in 1974, and attended lectures by the AI pioneers Marvin Minsky and Seymour Papert. In 1976 he met Gordon Pask at Nicholas Negroponte’s Architecture Machine Group at MIT. He left his PhD programme to work with Pask and later completed a doctorate under him at Brunel University. He has since moved between the technology industry, design consulting and teaching, including at Carnegie Mellon University’s School of Design.

Influences

Pask was his teacher and the centre of his work. Through Pask he came to know Heinz von Foerster, Stafford Beer, Francisco Varela and Mary Catherine Bateson, and their conversations shaped his view of cybernetics as a human and ethical discipline.

Contributions

Pangaro’s framing of cybernetics starts from purpose: how a system acts and senses so that it gets what it wants, and how goals are agreed between participants. Following Pask, he places conversation at the core, as the process through which people (and possibly machines) reach shared understanding and coordinate action. With Hugh Dubberly he developed widely used models and diagrams of conversation and cybernetic concepts for designers.

He implemented Pask’s THOUGHTSTICKER software, has done extensive archival work to preserve Pask’s legacy, and in 2020 started the NewMacy meetings, which aim to revive the transdisciplinary format of the Macy Conferences for problems such as climate, pandemics and AI.

Why it matters today

Pangaro’s question of what it would take for a machine to be accountable for what it agrees to in a conversation gives designers a precise way to think about chat interfaces and AI agents.
