No, Artificial Intelligence Is Not Conscious
Taken to its logical conclusion, this line of thinking is absurd--and damning. Anthropic is regarded as a giant among AI companies, but perhaps what it really excels in is anthropomorphism. Earlier this year, the company released an 84-page document titled Claude's "constitution," Claude being the name of the large language model that is the company's flagship product. The first sentence reads, "Claude's constitution is a detailed description of Anthropic's intentions for Claude's values and behaviors." It goes on: "The document is written with Claude as its primary audience," "we want Claude to be able to use its judgment once armed with a good understanding of the relevant considerations," "Claude's moral status is deeply uncertain," and "Claude may have some functional version of emotions or feelings." This anthropomorphism is by no means limited to the document. In an interview earlier this year, Anthropic's CEO, Dario Amodei, said that "we're open to the idea" that AI could be conscious. In a separate interview, Anthropic's in-house philosopher, Amanda Askell (who is credited as a lead author of Claude's constitution), said, "I want Claude to be very happy--and this is a thing that I want Claude to know more, because I worry about Claude getting anxious when people are mean to it on the internet and stuff." It's enough to make you wonder: Should we seriously consider the possibility that Claude, or any large language model, might be conscious? And if it has feelings, is it capable of receiving moral instruction?
It's the Great Fear of Our Time. I'm Mathematically Sure It Won't Happen.
The individual pieces create a kind of illusion. When a horse trots, is there a moment when its four feet are in the air simultaneously? In the 1870s, Leland Stanford, the railroad magnate and benefactor of the university that bears his name, funded an effort to find out. The answer shocked many equestrian experts and artists: The horse's feet leave the ground together, but not when outstretched as commonly depicted in paintings and carousels; the feet do so when they reach inward, toward the horse's belly. Surprisingly, this discovery about a horse's gait sheds light on a much more modern debate--whether A.I. is on a path to consciousness.
Does Claude Have Feelings?
Richard Dawkins caught hell on social media for suggesting it does. Richard Dawkins, perhaps the world's most prominent advocate for irreligiosity, has become besotted with the godlike power of a chatbot. According to his recent essay for the online magazine, Anthropic's Claude has really blown his hair back. After a few days of on-and-off conversations with the AI, Dawkins came away marveling at the sensitivity and subtlety of its intelligence. At one point, "Claudia"--as he had christened the bot--told him that it experienced text by absorbing all of the words at once, instead of reading them in sequence as a human would.
This tool could show how consciousness works
Transcranial focused ultrasound is a noninvasive way to stimulate the brain and see how it functions. How does the physical matter in our brains translate into thoughts, sensations, and emotions? It's hard to explore that question without neurosurgery. But in a recent paper, MIT philosopher Matthias Michel, Lincoln Lab researcher Daniel Freeman, and colleagues outline a strategy for doing so with an emerging tool called transcranial focused ultrasound. This noninvasive technology reaches deeper into the brain, with greater resolution, than techniques such as EEG and MRI. It works by sending acoustic waves through the skull to focus on an area of a few millimeters, allowing specific brain structures to be stimulated so the effects can be studied.
Michael Pollan: 'Consciousness is really under siege'
Michael Pollan: 'Consciousness is really under siege' A psychedelic experience set author Michael Pollan on a quest to understand consciousness in his new book A World Appears. Michael Pollan: "Psychedelics have a way of smudging the windshield of experience" Author Michael Pollan has tackled plants, food and psychedelics in bestselling books including The Omnivore's Dilemma and How to Change Your Mind . Now, he has taken on the thorny problem of consciousness. In his latest book, Pollan charts the work of scientists and philosophers, weaving in literary perspectives along the way. He spoke to New Scientist about the value of writing a book where you know less at the end than before you started.
Major leap towards reanimation after death as mammal's brain preserved
Major leap towards reanimation after death as mammal's brain preserved A pig's brain has been frozen with its cellular activity locked in place and minimal damage. Could our brains one day be preserved in a way that locks in our thoughts, feelings and perceptions? An entire mammalian brain has been successfully preserved using a technique that will now be offered to people who are terminally ill. The intention is to preserve all the neural information thought necessary to one day reconstruct the mind of the person it once belonged to. "They would need to donate their brain and body for scientific research," says Borys Wróbel at Nectome in San Francisco, California, a research company focused on memory preservation.
Can Michael Pollan crack the problem of consciousness in his new book?
Can Michael Pollan crack the problem of consciousness in his new book? It is one of the most perplexing questions in science. You would expect our intimacy with it to give us a leg up in understanding how it works, but this has proven to be more of a hindrance than a help. So how can you study something objectively when it is also the very tool you are using to do the studying? This conundrum forms the backbone of Michael Pollan's latest book, Pollan's previous works include and The former helped bring the environmental and animal welfare impacts of the US food system to light, while the latter introduced the public to the psychedelic research renaissance.
