This is the fourth in a series of posts on Jonathan Birch’s book, The Edge of Sentience. This one covers the section on artificial intelligence. Birch begins the section by acknowledging how counter intuitive the idea might be of sentience existing in systems we build, ones that aren't alive and have no body. But he urges us to … Continue reading The edge of sentience in AI
This is the third in a series of posts on Jonathan Birch's book, The Edge of Sentience. This one covers the section on animal sentience. I think it's fair to say that this is the section Birch is most passionate about. It's definitely the one where I feel his activism most keenly. A concept he … Continue reading The edge of sentience in animals
This is the second in a series of posts on Jonathan Birch's book, The Edge of Sentience. This one is on borderline cases of sentience in humans. Birch looks at cases involving humans with disorders of consciousness, such as those in vegetative or minimally conscious states, as well as fetuses, embryos, and neural organoids made … Continue reading The edge of sentience in humans
I'm currently reading Jonathan Birch's The Edge of Sentience, a book focusing on the boundary between systems that can feel pleasure or pain, and those that can't, and the related ethics. While this is a subject I'm interested in, I'm leery of the activism the animal portions of it attract. I have nothing in particular … Continue reading The semantic indeterminacy of sentience
Can the possibility of AI consciousness be ruled out? Anil Seth has a new preprint on the question of AI consciousness. Seth is skeptical about AI consciousness, although he admits that he can't rule it out completely. He spends some time attacking computational functionalism, the view that mental states are functional in nature, that they … Continue reading AI intelligence, consciousness, and sentience
This talk by David Chalmers on the relationship between consciousness and moral status is pretty interesting. You don't have to watch the video to follow this post, but it's in response to arguments he makes in the talk. The video is 75 minutes but the talk only lasts about 50 minutes with a Q&A afterward. … Continue reading Consciousness and moral status
Organoids, the small pieces of neural tissue grown from stem cells, dubbed "mini-brains", and used in research, have been getting a lot of attention lately. Apparently a few neuroscientists are concerned that the organoids might be sentient, and suffering as experiments are performed on them. There's growing concern that implanting human mini-brains in animal brains … Continue reading Angst over mini-brains
Smell has apparently always been a peculiar sense. The sensory pathway of smell information to the brain runs completely independent from the other senses. The pathways for the other senses run through the midbrain and thalamus and are then relayed to cortical regions. But smell goes to the olfactory bulb behind the nose, and from … Continue reading Did smell lead to consciousness?
I found this study interesting: Do flies have fear (or something like it)? -- ScienceDaily. A fruit fly starts buzzing around food at a picnic, so you wave your hand over the insect and shoo it away. But when the insect flees the scene, is it doing so because it is actually afraid? Using fruit flies … Continue reading Fruit fly fear and AI sentience
Click through for full sized version and the red button caption. via Saturday Morning Breakfast Cereal. This SMBC reminds me of a concept that I've been debating on ways to express, but a brief comment here seems like the opportunity to do so. We've had a lot of discussions about exactly when we might start to … Continue reading Emotional versus intellectual attributions of consciousness
