The AI + Planetary Justice Alliance joined researchers, organizers, and practitioners in Bengaluru for the Mapping Data Work workshop — a gathering that foregrounded the invisible labor behind AI systems. In our blog, we report key takeaways, reflect on what it means to build “ethical datasets,” question the assumptions behind datafication, and share insights from our own research on epistemic justice in agricultural AI in India. What if the push to represent is just another form of surveillance? And why are we building AI in the first place? Read the full piece to explore the planetary justice implications of some of AI’s quietest supply chains: data work.
