Experienced sensations while reading: frustration, dread, restless legs, and overwhelming waves of weariness. At one point I felt physically nauseous.
I’ve been trying to figure out why, since (a) Michael Pollan is a great writer who has proven his chops over countless other topics, and (b) this is objectively quite a good book about the science of consciousness. Indeed, I should be happy! Consciousness is clearly having “a moment” right now—a science book about consciousness has been on The New York Times bestseller list for nine weeks, and meanwhile, the online world is abuzz with debates about AI consciousness.
And yet… I hated Pollan’s book.
I felt that every next chapter or section could have been predicted by some statistical machine for producing books about consciousness (“Okay, here’s the part about David Chalmers coming up”). And yes, I have the advantage of being a researcher in the same subject and have even worked with some of the figures Pollan writes about, which is why in my own The World Behind the World (we all seem to gravitate to the same titles, huh) I broadly told much the same story. But you can even go back to science journalist John Horgan’s The Undiscovered Mind, published in 1999, to get similar progress beats and quite familiar names. It’s been 27 years, during which the discussion has (as many fields of science do) centered around major figures like neuroscientists Christof Koch or Giulio Tononi or Antonio Damasio or philosophers like David Chalmers. There’s always the part where Alison Gopnik makes an appearance. Karl Friston pops his head in. And all these people are intellectual titans. Truly. But honestly, this stage of consciousness research feels played out.
Like you have Christof Koch, one of the highest-profile figures, who broke open the field in the 1990s with Francis Crick (co-discoverer of DNA’s structure) and gave one of the first proposals for a neural correlate of consciousness: gamma oscillations in the ~40Hz range in the cortex.
Koch, who is soon to turn seventy, was for a while after the death of Francis Crick a staunch supporter of Integrated Information Theory (I was part of the team that worked on developing that theory after Giulio Tononi proposed it, and even once did a conference submission with Koch himself). But now Koch has apparently moved on to other approaches to consciousness, mentioning his attendance of an ayahuasca ceremony and his accessing of a “universal mind.”
Here’s Pollan talking to Koch at the end of the book:
When I confessed to Koch my fear—that after my five-year journey into the nature and workings of consciousness, I somehow knew less than I did when I started—he simply smiled.No, it isn’t!
“But that’s good,” he said. “That’s progress.”
Consciousness is not here for our personal therapy. It’s not tied to our life journeys. And I’m guilty of all that artsy and personal stuff too! But it’s no longer about how the grand mystery makes us feel, or the friends we made along the way.
It’s all changed.
HOW WE FAILED
Right now, there’s some college student falling in love with a chatbot instead of the young woman who sits next to him in class, all because science literally cannot tell him that the chatbot is lying about experiencing love. On the other hand, if somehow AIs are conscious, either right now (to some degree), or near-future ones will become so, then they deserve rights and protections, and the entire legal and social apparatus of our civilization must expand rapidly to include radically different types of minds (or we must choose to restrict what kinds of minds we create). There are immediate practical matters here. Long term, we also need to protect against extremely bad futures where only non-conscious intelligences remain—the worst of all possible worlds is that our civilization acts like a reverse metamorphosis, where something weaker but more beautiful, organic consciousness, gets shed in the birth of some horrible star-devouring insect made of matrix multiplication. And then it turns out there is nothing it is like to be two matrices multiplying.
While it’s my opinion that modern LLMs operate more like tools right now, or at best like a lesser statistical approximation of what a good human output would be (with their main advantage being search, not insight), this is all just the beginning of the technology. The door is open and will never be closed again.
Of course, consciousness matters far beyond just AI. Table stakes for actual scientific progress on consciousness include shifting neuroscience and psychiatry from pre-paradigmatic to post-paradigmatic sciences (and all the pile-on effects from that). This was always true. But my point here is that LLMs act like a forcing function. Before everything changed, consciousness research was an unhurried subfield of neuroscience that was always a little weird and niche; therefore academics are guilty of treating consciousness like an academic exercise. [...]
Due to the rise of behaviorism and logical positivism, “consciousness” became a dirty word in science for half a century or more—precisely when the rest of the sciences rocketed ahead! The consciousness winter only really ended in the 1990s because of the collective weight of several Nobel Prize winners (like Francis Crick and Gerald Edelman) determined to make it acceptable again.
The two major scientific conferences (which are how scientists organize) devoted to consciousness also only started in the mid-90s. That’s just 30 years ago! Modern science is incredibly powerful, maybe the most powerful force in existence, but in the grand scheme of things, 30 years is not long at all. That’s just one generation of scientists and thinkers. Kudos to them. Pretty much all of the big names (including definitely Koch) deserve their laurels, and contra Pollan, I do think consciousness actually has made progress over the last 30 years, in that our conceptions are a lot cleaner, the definitional problem is pretty much solved, a lot of the space of initial possible theories is mapped, the problems and difficulties are much better known and clearly outlined, and there is organizational and behind-the-scenes structure that exists in the form of established conferences and labs and minor amounts of funding, etc.
And that’s another thing: no one has tried throwing money at the consciousness problem, at all—and for many problems, from AI to cancer cures, a necessary component often ends up being finance and scale and concentrating talent.
Humanity spends something like a billion dollars a year on CERN. To compare, let’s look at the biggest scientific funder in the United States, the NIH. Out of 103,280 grants awarded to scientists during the 2007-2017 decade, want to guess how many were about directly studying the contents of consciousness?
Five.
That’s probably, at most, a couple million dollars in funding over a decade. Total. So if you’re a consciousness researcher, what can you do, cheaply? What can you do, for free? You can pontificate. You can propose your own theory of consciousness! That requires no funding whatsoever. And so for 30 years the meta in consciousness research has been to create your own theory of consciousness. We’ve let a thousand flowers bloom. The problem is that, if any flower is at all true or promising, you can’t identify it, as its sweet subjectivity-solving scent is completely masked by the bunches of corpse flowers around it. We have too many flowers, and one more just isn’t meaningful anymore. As is sometimes said at the end of fairy tales: “Snip, snap, snout. This tale’s told out.”
What we need are efforts at field-clearing, and methods that can actually make progress on consciousness in ways not tied to just promoting or trying to find evidence for some pre-chosen pet theory—which means finding ways to select over theories, to test theories en masse, so you don’t reinvent the wheel each time, and, perhaps most importantly, you have to do all this while scaling institutions with funding to specifically get a bunch of smart people in a room working together on this.
If the 2020s were all about intelligence, then necessarily the 2030s will be all about consciousness. Intelligence is about function, while consciousness is about being, and forays and progress into understanding (and shaping) function will in turn force our attention toward a better understanding of being. And if the answer to “Why has consciousness not been solved?” is secretly “Material and historical conditions made it hard for anyone to actually try!” then the answer is to actually try.
I refuse to live in a civilization where we consciousness researchers have so obviously failed. I refuse to live in a civilization where we cannot tell consciousness from non-consciousness. Where we can offer no guidance for the future. Where we cannot explain the difference between actually experiencing things vs just processing them. In the short term, this is destabilizing and harmful. In the long term, it may be literally existentially dangerous.
