Excellent survey of the variety of views on artificial consciousness My contribution draws on the importance of unity for conscious experience & suggests this depends on the metabolic unity of an organism: leaflet.pub/p/did:plc:ct... Thanks to @anilseth.bsky.social for such a rich target article!
leaflet.pub
Absolute Units: The metabolic basis of the experiential self
Commentary on Seth (2025): Unity is intrinsic to being both an experiencing and an embodied subject. Computational accounts of consciousness, being observer-relative, cannot account for this unity. The thermodynamics of life can but, contra Seth’s suggestion, the free energy principle fails to capture the distinctive metabolic interdependencies by virtue of which a living system constitutes itself as a unified perspective on the world.

“Air pollution fell substantially as Paris restricted car traffic and made way for parks, people-streets and bike-lanes.” Better for the climate, better for health, better for livability and quality of life. Common sense. Such a no-brainer, it’s remarkable that more cities HAVEN’T done the same.

Does ingroup love lead to outgroup hate? I often tell people that identifying with ingroups does not always lead to outgroup discrimination. I call this the "Myth of tribalism". A new paper provides strong and robust evidence for a positive relationship between ingroup and outgroup prosociality.!

Intestinal interoceptive dysfunction drives age-associated cognitive decline | Nature
Aging is accompanied by declining memory function, with extremely heterogeneous manifestation in the human population1. Brain-extrinsic factors influencing cognitive decline, such as gastrointestinal signals, have emerged as attractive targets for peripheral interventions2–6, but the underlying mechanisms remain largely unclear. Here, by charting a high-resolution map of microbiome ageing and its functional consequences throughout the lifespan of mice, we identify a mechanism by which inhibition of gut–brain signalling during ageing results in impaired neuronal activation in the...
