Seven years after they started, neuroscientists have published the results of a landmark study that was designed to determine which theory of human consciousness came closest to the mark — and those results are decidedly mixed.

The bad news is that neither of the leading theories held a clear advantage in explaining how consciousness arises. The good news is that researchers picked up new clues about where to look.

One of the leaders of the effort — Christof Koch, a meritorious investigator at the Seattle-based Allen Institute — said he was heartened by the state of the debate.

“Adversarial collaboration fits within the Allen Institute’s mission of team science, open science and big science, in service of one of the biggest, and most long-standing, intellectual challenges of humanity: the Mind-Body Problem,” Koch said in a news release. “Unraveling this mystery is the passion of my entire life.”

Why it’ll get harder to draw the line between AI and us

Some say artificial intelligence will be humanity’s greatest helper. Others warn that AI will become humanity’s most dangerous rival. But maybe there’s a third alternative — with AI agents achieving the status of personhood alongside their human brethren.

The potential for that scenario is the focus of a newly published book titled “The Line: AI and the Future of Personhood.” The author, Duke University law professor James Boyle, says the book has been more than a decade in the making — which suggests more than the usual prescience about the tech world’s current fascination with AI.

In the latest episode of the Fiction Science podcast, he recalls the reaction he received when he shared his early ideas about the book with federal judges more than a dozen years ago..

“They’re like, ‘Rights are reserved for humans, naturally born of women!’ OK, well, not necessarily a great crowd,” says Boyle, founder of Duke Law School’s Center for the Study of the Public Domain. “Obviously, things have changed since then. The book seems perhaps less unhinged now than it did then.”

AI experts look ahead to artificial general intelligence

There’s no question that artificial intelligence is rapidly becoming more intelligent, thanks to software platforms including ChatGPT, Google Gemini and Grok. But does that mean AI agents will one day outdo the generalized smarts that distinguish human intelligence? And if so, is that good or bad for humanity? Those were just a couple of the questions raised during this week’s AGI-24 conference in Seattle.

Conference sessions at the University of Washington centered on a concept known as artificial general intelligence, or AGI. Artificial intelligence can already outperform humans on a growing list of specialized tasks, ranging from playing the game of Go to diagnosing some forms of cancer. But humans are still more intelligent than AI agents when it comes to dealing with a wider range of tasks, including tasks they haven’t been trained to do. That’s what AGI is all about.

David Hanson, a roboticist and artist who’s best known for creating a humanoid robot named Sophia, said the questions surrounding human-level intelligence and consciousness are a high priority for his team at Hanson Robotics.

“The goal really is continuously to explore what it means to be intelligent,” he said during an Aug. 16 session. “How can we achieve consciousness? How can we make machines that co-evolve with humans? All of these efforts, while they’re really cool, and I’m very proud of them, they’re all just trying to get the engine to start on this kind of conscious machine that can co-evolve with humans.”

How AI and quantum physics link up to consciousness

Will artificial intelligence serve humanity — or will it spawn a new species of conscious digital beings with their own agenda?

It’s a question that has sparked scores of science-fiction plots, from “Colossus: The Forbin Project” in 1970, to “The Matrix” in 1999, to this year’s big-budget tale about AI vs. humans, “The Creator.”

The same question has also been lurking behind the OpenAI leadership struggle — in which CEO Sam Altman won out over the nonprofit board members who fired him a week earlier.

If you had to divide the AI community into go-fast and go-slow camps, those board members would be on the go-slow side, while Altman would favor going fast. And there have been rumblings about the possibility of a “breakthrough” at OpenAI that would set the field going very fast — potentially too fast for humanity’s good.

Is the prospect of AI becoming sentient and taking matters into its own hands something we should be worried about? That’s just one of the questions covered by veteran science writer George Musser in a newly published book titled “Putting Ourselves Back in the Equation.”

Musser interviewed AI researchers, neuroscientists, quantum physicists, neuroscientists and philosophers to get a reading on the quest to unravel one of life’s deepest mysteries: What is the nature of consciousness? And is it a uniquely human phenomenon?

His conclusion? There’s no reason why the right kind of AI couldn’t be as conscious as we are. “Almost everyone who thinks about this, in all these different fields, says if we were to replicate a neuron in silicon — if we were to create a neuromorphic computer that would have to be very, very true to the biology — yes, it would be conscious,” Musser says in the latest episode of the Fiction Science podcast.

But should we be worried about enabling the rise of future AI overlords? On that existential question, Musser’s view runs counter to the usual sci-fi script.

‘Observer’ blends way-out quantum science and fiction

Do we each create our own reality? Could different observers create measurably different realities? It’s a fantastical line of thought that has sparked scientific inquiries as well — and now the science and the fiction has come together in a new novel titled “Observer.”

“The observer is actually the basis of the universe, so basically the novel and the scientific ideas are really a rethink of everything we know about time, space and indeed the universe itself,” stem-cell researcher Robert Lanza says in the latest episode of the Fiction Science podcast.

Lanza’s co-author, Seattle science-fiction writer Nancy Kress, agrees that the novel takes aim at one of life’s greatest mysteries. “The novel is about how we understand reality, and nothing could be more important about that, because everything else is based on it,” she told me.

What octopus intelligence teaches us about AI and aliens

Are intelligent aliens living among us? A newly published novel just might lead you to think so — and in this case, the aliens aren’t visitors from another planet.

Instead, they’re octopuses, the eight-legged denizens of the deep that are celebrated in movies (including the Oscar-winning documentary “My Octopus Teacher”) and on the ice rink (thanks to the Kraken, the Seattle hockey team that’s getting set for its second NHL season.)

Ray Nayler, who wrote the novel titled “The Mountain in the Sea,” says he chose the octopus to serve as the designated alien for his science-fiction plot in part because it’s “a creature that has a structure totally different from ours, but in whom we recognize curiosity, which is what I think we find often most human in ourselves.”

Nayler doesn’t stop there: The promises and perils of artificial intelligence also figure prominently in the plot — in a way that sparks musings about how we’ll deal with AI, with kindred species on our planet, and perhaps eventually with extraterrestrial intelligence as well.

Dominic Sivitilli, a neuroscientist and astrobiologist at the University of Washington, says such musings are what led him to focus his studies on octopuses. “I suddenly had this model for what intelligence might look like, had it had a completely different evolutionary origin … possibly on another world, in another solar system,” he says. “And so they became a bit of a model to me for what extraterrestrial intelligence might end up looking like.”

Nayler and Sivitilli discuss animal intelligence, artificial intelligence and the prospects for cross-species communication in the latest episode of Fiction Science, a podcast that focuses on the intersection of science, technology, fiction and culture.

Scientist takes a trip to the frontiers of consciousness

Could magic mushrooms hold the key that unlocks the secrets of consciousness?

Well, maybe not the only key. But Allen Institute neuroscientist Christof Koch says that hallucinogenic drugs such as psilocybin, the active ingredient found in special types of mushrooms, can contribute to clinical research into the roots of depression, ecstasy and what lies beneath our sense of self.

“What they can teach us about consciousness is that the self is just one aspect of consciousness,” Koch says in the latest episode of the Fiction Science podcast. “You’re still highly conscious, and very often this is associated with states of ecstasy, or states of fear or terror, or a combination of ecstasy and terror. … What’s remarkable is that in all of these states, the self is gone, and very often the external world is gone, yet you’re highly conscious.”

The quest to understand consciousness through detailed analysis of the brain’s structure and function, scientific studies of religious and traditional practices — and yes, research into the effects of psychedelic drugs — is the focus of a 102-minute documentary film titled “Aware: Glimpses of Consciousness.”

“Aware” has been on the film-festival circuit for weeks, and an online showing will be the centerpiece of a live-streaming event set for Nov. 10. The documentary will also air on PBS stations next April as part of public TV’s Independent Lens series.

Koch, who’s the chief scientist of the Seattle-based Allen Institute’s MindScope brain-mapping program, is one of the stars of the show.

Do animals possess consciousness? Can consciousness be uploaded into a computer? Can we measure objectively whether someone is conscious or not?

Those may sound like deep, imponderable questions — but in a newly published book, “The Feeling of Life Itself,” neuroscientist Christof Koch actually lays out some answers: Yes, no … and yes, scientists are already testing a method for measuring consciousness, with eerie implications.

Along the way, Koch addresses brain-teasing concepts ranging from the Vulcan mind melds seen on “Star Trek” to the kind of brain-computer interface that billionaire Elon Musk is backing through his Neuralink venture.
