ChatGPT can’t think – consciousness is something entirely different to today’s AI

Illus_man / Shutterstock By Philip Goff, Durham University There has been shock around the world at the rapid rate of progress with ChatGPT and other artificial intelligence created with what’s known as large language models (LLMs). These systems can produce text that seems to display thought, understanding and even creativity. But can these systems really think and understand? This is not a question that can be answered through technological advance, but careful philosophical analysis and argument tells us the answer…

Consciousness begins with feeling, not thinking

Consciousness begins with feeling, not thinking

Antonio Damasio and Hanna Damasio write: Please pause for a moment and notice what you are feeling now. Perhaps you notice a growing snarl of hunger in your stomach or a hum of stress in your chest. Perhaps you have a feeling of ease and expansiveness, or the tingling anticipation of a pleasure soon to come. Or perhaps you simply have a sense that you exist. Hunger and thirst, pain, pleasure and distress, along with the unadorned but relentless feelings…

Why are most of us stuck with a belief in the soul?

Why are most of us stuck with a belief in the soul?

David P Barash writes: Few ideas are as unsupported, ridiculous and even downright harmful as that of the ‘human soul’. And yet, few ideas are as widespread and as deeply held. What gives? Why has such a bad idea had such a tenacious hold on so many people? Although there is a large literature on the costs and benefits – psychological and economic – of traditional religion, there is a dearth of comparable research on religion’s near-universal handmaiden, the soul….

How blindsight answers the hard problem of consciousness

How blindsight answers the hard problem of consciousness

Nicholas Humphrey writes: The cover of New Scientist magazine 50 years ago showed a picture of a rhesus monkey, with the headline ‘A Blind Monkey That Sees Everything’. The monkey, named Helen, was part of a study into the neuropsychology of vision, led by Lawrence (Larry) Weiskrantz in the psychology laboratory at the University of Cambridge. In 1965, he had surgically removed the primary visual cortex at the back of Helen’s brain. Following the operation, Helen appeared to be quite…

The human mind is not meant to be awake after midnight, scientists warn

The human mind is not meant to be awake after midnight, scientists warn

Science Alert reports: In the middle of the night, the world can sometimes feel like a dark place. Under the cover of darkness, negative thoughts have a way of drifting through your mind, and as you lie awake, staring at the ceiling, you might start craving guilty pleasures, like a cigarette or a carb-heavy meal. Plenty of evidence suggests the human mind functions differently if it is awake at nighttime. Past midnight, negative emotions tend to draw our attention more…

The mysterious inner life of the octopus

The mysterious inner life of the octopus

Martha Henriques writes: It was a big night for Inky the octopus. The day’s visitors had been and gone, and now his room in the aquarium was deserted. In a rare oversight, the lid of his tank had been left ajar. The common New Zealand octopus had been without female company for some time, sharing a tank with only a fellow male, Blotchy. The loose lid provided Inky with an opportunity. With eight strong suckered limbs and, quite possibly, intimate…

The octopus dreams of crabs

The octopus dreams of crabs

Laura Miller writes: John James Audubon was wrong. The great naturalist may have illustrated and compiled 1827’s Birds of America, a pioneering work of ornithology, but thanks to a series of sloppy experiments on turkey vultures, he insisted that birds can’t smell. This was taken for granted until the 1960s when two women scientists in New Zealand proved otherwise, but we are still discovering just how discerning bird’s noses can be. In the 1990s, biologist Gabrielle Nevitt was puzzling, as…

How I started to see trees as smart

How I started to see trees as smart

Matthew Hutson writes: A couple of decades ago, on a backpacking trip in the Sierra Nevada, I was marching up a mountain solo under the influence of LSD. Halfway to the top, I took a break near a scrubby tree pushing up through the rocky soil. Gulping water and catching my breath, I admired both its beauty and its resilience. Its twisty, weathered branches had endured by wresting moisture and nutrients from seemingly unwelcoming terrain, solving a puzzle beyond my…

Evidence is building that insects, octopus and other invertebrates feel emotions

Evidence is building that insects, octopus and other invertebrates feel emotions

ABC News (AU) reports: Up until the mid-1980s, human babies didn’t feel pain. Of course that’s not actually true, but due to research conducted in the 18th and early 19th centuries, it was an attitude that still lingered among a small minority of scientists and medical professionals. So much so that some infant surgery was still conducted without, or with very little, anaesthesia in the US into the ’80s. Today, the question of physical and emotional experience has moved beyond…

The man rethinking the definition of reality

The man rethinking the definition of reality

Tom Chatfield writes: If you woke up one day and discovered that you were living in a virtual world – that everything you’d ever known was, like the Matrix, a form of hyper-realistic simulation – what would this imply for your hopes, dreams and experiences? Would it reveal them all to be lies: deceptions devoid of authenticity? For most people, the intuitive answer to all these questions is “yes”. After all, the Matrix movies depict a dystopian nightmare in which…

I feel, therefore I am

I feel, therefore I am

Antonio Damasio writes: In the beginning was not the word; that much is clear. Life sailed forth without words or thoughts, without feelings or reasons, devoid of minds or consciousness. Not that the universe of the living was ever simple, quite the contrary. It was complex from its inception, four billion years ago. But living organisms then took several paths. In the branch of life history that led to us, I like to imagine three distinct and consecutive evolutionary stages….

Your attention didn’t whither away. It was stolen

Your attention didn’t whither away. It was stolen

Johann Hari writes: I went to Portland, Oregon, to interview Prof Joel Nigg, who is one of the leading experts in the world on children’s attention problems, and he told me we need to ask if we are now developing “an attentional pathogenic culture” – an environment in which sustained and deep focus is harder for all of us. When I asked him what he would do if he was in charge of our culture and he actually wanted to…

Can lab-grown brain organoids be ‘conscious’? Scientists may soon find out

Can lab-grown brain organoids be ‘conscious’? Scientists may soon find out

Anil Seth writes: In 2022 we will see brain organoids displaying dynamics that bear comparison with the complex activity patterns indicative of consciousness in humans. This will require us to rethink what counts as a brain signature of “consciousness” and will raise serious ethical issues about brainlike structures grown in the lab. Brain organoids are tiny, lab-grown bundles of neurons, derived from human stem cells, that display various properties of the developing human brain. In medicine, they provide much-needed biological…

The brain has a team of conductors orchestrating consciousness

The brain has a team of conductors orchestrating consciousness

Morten L Kringelbach writes: The execution of any musical symphony is a difficult task, demanding significant skills from each musician. Perhaps the hardest task lies with the conductor who must orchestrate the musicians so the music comes alive cohesively and speaks to our deepest emotions. The human brain is like an orchestra: different regions perform different types of processing, much like the individual musicians who must read the music, play their instruments, and also listen and adapt to the sounds…

Having a concept of death is far from being a uniquely human attribute

Having a concept of death is far from being a uniquely human attribute

Susana Monsó writes: Humans have long thought of themselves as the only animal with a notion of mortality. Our concept of death is one of those characteristics, like culture, rationality, language or morality, that have traditionally been taken as definitional of the human species – setting us apart from the natural world and justifying our boundless use and exploitation of it. However, as I have argued elsewhere, the widespread notion that only humans can understand death stems from an overly…

On the evidence for fungal intelligence

On the evidence for fungal intelligence

Nicholas P Money writes: Mushrooms and other kinds of fungi are often associated with witchcraft and are the subjects of longstanding superstitions. Witches dance inside fairy rings of mushrooms according to German folklore, while a French fable warns that anyone foolish enough to step inside these ‘sorcerer’s rings’ will be cursed by enormous toads with bulging eyes. These impressions come from the poisonous and psychoactive peculiarities of some species, as well as the overnight appearance of toadstool ring-formations. Given the…
