The next decades will transform animal welfare through cultivated meat, welfare technology, AI monitoring, and expanding moral circles. Understanding these trajectories helps advocates prepare for the most impactful interventions.
The future of animal welfare will likely be shaped by technological substitution, monitoring advances, and paradigm shifts in how we relate to other species. Cultivated meat and precision fermentation could eventually make the farming of billions of animals unnecessary, addressing welfare problems at the source rather than managing them within existing systems. AI monitoring that continuously tracks behavioral welfare indicators in large populations could make welfare assurance achievable at scale in ways that periodic human inspection cannot. The expansion of moral circles to include fish, invertebrates, and wild animals reflects ongoing scientific and philosophical development that will ultimately reshape welfare obligations. Effective advocates today should invest in both immediate welfare improvements and the systemic changes that will define the next century of human-animal relations.
