The Body and Technology: Vanessa Chang on Design Justice and Embodiment

Overview

In this episode, Scientific American host Andrea Garleski chats with Vanessa Chang about her book on humans and machines, examining how technologies shape our bodies and movements from writing to smartphones and urban spaces. The conversation centers on design justice, accessibility, and the social implications of technology in everyday life.

Key insights

• Technology as embodiment: writing and keyboards train our bodies, teaching movements that persist beyond life.
• Uncanny and anxiety: historic fears around lifelike machines reveal deep concerns about creativity and human value.
• Design justice: inclusive design requires involving disabled people, language diversity, and culturally attuned interfaces.
• Daily life and data: personalization and data use can homogenize culture and limit exposure to new ideas.

Introduction and core theme

The podcast features Scientific American host Andrea Garleski discussing with Vanessa Chang, director at Leonardo, the International Society for the Arts, Sciences and Technology, about her book The Body A Brief History of Humans and Machines from cuckoo clocks to ChatGPT. The central claim is that technology is not neutral and continually shapes human embodiment. The discussion follows a deliberate trajectory from the most intimate interfaces to large-scale urban design, all framed through a design justice lens.

Technology and the body

Chang outlines a historical and practical view of how tools become an extension of the body. She starts with the hands as the primary interface with technology and expands to the mind’s engagement with writing as a technology. Writing is described as choreography of the body, a skill learned through discipline much like typing. The QWERTY keyboard remains embedded in our bodies even if it is not ergonomically optimal, because it has trained our movements and gestures. This leads to a broader worry: modern technologies, though powerful, can discipline our bodies in ways that are brand and platform specific, potentially limiting expressive possibilities and the persistence of human creativity beyond death through digital traces.

Automation, uncanny feeling, and culture

The conversation moves to the familiar theme of the uncanny valley, tracing early automatisms such as the Jacquard loom and Renaissance automatons. Chang explains how these devices triggered anxiety about displacement of human creativity and the fear that machines could encroach on uniquely human acts like writing and music. The Jacquard loom, as a precursor to computation via punch cards, is highlighted to show a lineage from crafts to computing, and how such technologies simultaneously streamlined labor and threatened traditional craftsmanship.

AI, grief, and ethical design

The discussion touches on contemporary AI challenges, including grief bots and holographic representations. Chang emphasizes that while such technologies offer new forms of connection and coping, they also risk displacing genuine human contact. The conversation pushes back against a purely market-driven approach to design, advocating for attention to the social costs and relational implications of AI that simulates intimacy or consolation.

Design justice and disability

A central theme is design justice, which requires involving disabled people in the creation and evaluation of technologies. The host and guest discuss Alice Wong’s work on text-to-speech and the Anglocentric bias embedded in many interfaces. The interview highlights captioning, language, and accessibility as critical design considerations that should be foregrounded rather than retrofitted.

Cities, sidewalks, and inclusion

The Rolling Quads from Berkeley are cited as a landmark example where curb cuts were demanded and ultimately implemented, illustrating how urban design can advance equal participation in public life. Chang broadens the scope to show how city planning encodes ideas about the “ideal body” and how inclusive infrastructure—crosswalks, sign systems, and pedestrian-friendly streets—enables full participation in civic life. The discussion underscores the need for culturally and linguistically inclusive digital ecosystems that reflect diverse user needs.

Conclusion and implications

The podcast closes with reflections on how readers can engage with technology more consciously, participate in the design process, and advocate for systems that respect diverse bodies and life experiences. The overarching message is a call to embed design justice and disability perspectives into technology, policy, and urban design so that tech serves inclusion rather than conformity.
