ALIFE 2025 Workshop
Mortal Agents in ALIFE:
Physical, Psychological, and Social Death in the Machine
This workshop explores cognitive processes from the perspective of Mortal Agents—creature-agents with physical bodies, psychological minds, and finite lifespans. Survival is fundamental in nature, as seen in Ashby’s ultrastable systems (homeostasis) and Varela & Maturana’s autopoiesis, both of which frame life as an ongoing process of maintaining stability and resisting decay. With advanced AI and robotics emerging, this workshop examines the implications of mortality in artificial systems.
There are three key reasons for hosting this workshop at ALIFE:
1. Relevance to ALIFE Research ALIFE has long studied agent survival through research such as homeodynamics, homeostatic adaptation, and evolutionary optimization. The Mortal Agents perspective builds on these themes, enriching contemporary discussions.
2. ALIFE’s Broad Perspective on Life Phenomena While homeostasis and mortality in artificial intelligence remain underexplored, they are gaining attention. ALIFE’s life-as-it-could-be framework fosters discussions on survival and death in artificial systems. Our invited speaker will examine these implications.
3. ALIFE as a Bridge Between Science, Art, and Life Robots exist as research tools, artistic expressions, and consumer products (e.g., ERICA, aibo, LOVOT). Yet, all face eventual functional limits and cessation. A panel discussion will explore their life-like qualities through interviews with artists.
This workshop invites researchers from artificial life, robotics, neuroscience, AI, and art to discuss life’s essence in creature-agents and the intelligence that resists death.

Pre-Meeting Materials
Due to the time limitation of the time slot of the workshop, we strongly encourage all participants to watch his artworks before the meeting.
Takayuki Todo's Artworks (adopted from his homepage)
"Dynamics of a Dog on a Leash" is an installation work that displays an autonomous 4 legged robot dog that is about to attack people, bound by a chain in a restricted state. The viewers face the "murderous gaze" of the robot while keeping a safe distance from the robot's attacks. Although it already has sufficient athletic ability and lethal power, this artificial beast is barely under control by a single "chain of ethics." Will it appear as a "living other" to the humans whom it glares at? (from https://www.takayukitodo.com/)
SEER is a humanoid robotic head that explores how gaze and facial expression foster emotional connection between humans and machines. Rather than relying on humanlike realism, it emphasizes eye contact and mirrored expressions to soften the uncanny valley. With a simplified, childlike face, SEER uses cameras and subtle movements of the eyes, eyelids, eyebrows, and head to reflect the viewer, creating a tender sense of liveliness without autonomous gestures.
