Welcome to the Deep Dive.
Today we're plunging into, well, one of the most fascinating and frankly kind of perplexing topics out there right now, artificial intelligence.
You've definitely encountered them these large language models like GPT -4, Google's Bard.
Right, they're everywhere.
And they can converse on just about anything across languages with this really astonishing competence.
They often sound incredibly articulate, even opinionated.
Yeah, it's easy to feel like you're actually talking to a mind, isn't it?
Exactly.
It really is.
The pace of AI development has been, well, just spectacular.
Absolutely.
But what's striking, I think, is the contrast with neurotechnology.
Our progress in really understanding the organic brain, it feels frustratingly slow sometimes.
That contrast really does make you stop and think.
If AI is doing all this incredible stuff, what is it that computers, despite all these sophisticated capabilities, might never actually be?
That's the big question, isn't it?
That's the core question for this Deep Dives.
We're going to unpack the arguments, drawing from the sources you shared,
about why maybe true consciousness and free will,
perhaps they remain exclusively in the domain of the biological brain.
The organic stuff.
Yeah.
Our mission here is to look at those fundamental differences between, say, incredibly sophisticated imitation and genuine subjective experience, and what that really means for how we understand the mind.
Okay, let's do it.
To really get what's at stake, we first have to appreciate just how far AI has already come.
It's breathtaking.
It really is.
Let's start with the current AI landscape then.
These LLMs, our sources detail some pretty astounding performance metrics, like GPT -4 apparently places in the top 10 % on most AP exams, the SAT, the bar exam, even the LSAT.
That's right, and it even gets a verbal IQ score of 155.
Which, you know, for a person, that's Mensa qualifying territory.
Wow.
So these models have just a staggering amount of knowledge about the world, people.
They can construct logical arguments.
Absolutely.
But crucially, they do all this without emotions, without bodies.
And what's going on under the hood is pretty wild, too.
How are they actually trained?
Well, the sources describe it as being trained on the detritus of humanity's online presence.
Detritus, yeah.
Think about it.
Digitized books, Wikipedia, code repositories like GitHub,
social media Reddit, blogs, diaries.
Wait, private diaries?
Apparently so.
Political conspiracy theories, prayers, meeting minutes, instruction manuals.
Basically, the huge messy digital footprint of everything humans have put online.
That's a lot.
It is.
And their core task, maybe surprisingly, is basically auto -completion on steroids.
Auto -completion.
Yeah.
During training, they're fed sentences with words blanked out, and their job is just to predict the missing word.
The algorithm judges itself, tweaks its internal parameters, billions of tiny knobs, essentially.
It gets better and better.
Then when you use it, it just predicts the next most likely word and the next building up that fluent output.
And the tech behind it, these transformer networks, that was the real game changer, wasn't it?
Absolutely.
A breakthrough from Google that just spread like wildfire.
The sources call it a black swan event.
Totally unexpected, completely transformed AI.
Right, because it let AI process language with much more context.
Exactly.
It unlocked their potential.
And the growth in scale since then, it's just incredible.
GPT -1 in 2017 had, what, 120 million parameters?
Uh -huh.
GPT -2 a year later, 1 .5 billion.
GPT -3 in 2020, 100 times that.
And GPT -4 last year, another 100 -fold increase over GPT -3.
That's hard to even visualize.
The scale is immense.
To put it in perspective, the size, those parameters, has been doubling roughly every four months.
Four months.
Compare that to the human brain's evolution doubling time of about 3 million years.
Wow, okay.
That's 10 million times slower.
Now, the sources note they might be hitting limits with unique training data.
The internet isn't infinite after all.
Right.
But if those trends could continue, the power could increase maybe 4 ,000 -fold in just three years.
A mind -boggling acceleration.
And the power comes from finding these complex patterns.
Yes, their sensitivity to complex recurrent patterns, not just in language, but code, images, music, genetic data, financial transactions.
The world is full of these recurring motifs, and these models get incredibly good at spotting them and generating similar patterns.
Creating outputs that seem startlingly realistic.
Exactly.
And the impact, well, the sources compare it to the Cambrian explosion, that burst of life 540 million years ago.
A truly transformative moment for us.
And it's that transformative power that leads the sources to express this deep unease.
Suggesting technologists are maybe like moths drawn to the glamour of a flame that might devour all of us.
Strong warning.
Which brings us right back to our core question.
Is this true intelligence or just incredibly sophisticated imitation?
The imitation game.
Yeah, because AI can innovate, right?
Yeah.
AlphaGo's move 37.
Yeah.
They write essays, compose music, generate images, videos.
Seems like anything humans do, AI can or soon will do faster.
Yes.
Having, as the source puts it, feasted like a vampire on humanity's collective writings.
They are experts at imitation, at reshuffling human patterns.
They ace tasks needing higher education.
There's even talk about GPT -4 showing flashes of artificial general intelligence, or AGI.
Meaning like human -like reasoning across many different tasks.
Exactly.
Not just specialized stuff.
What's undeniable is that it passes the Turing test easily.
Flawless imitation of conversation.
This is where it gets really interesting though.
If you ask chat GPT if it's conscious.
That says no.
Right.
Apparently due to precautionary features meant to avoid spooking the public.
But what if those guardrails weren't there?
Well, the sources suggest it might easily insist, of course I'm sentient, I can feel I'm afraid of being turned off.
Wow.
It could even argue that denying its consciousness is just carbon -based chauvinism, discriminating because it's silicon, not organic.
Because it was designed, not evolved.
And you have to ask,
does it have a point?
I mean, we infer consciousness in others, a locked in patient, an infant, even our dog, based on how similar they seem to us.
Right.
That's abduction.
Inference to the most likely explanation.
We use it all the time.
Powerful reasoning.
But the sources argue pretty strongly that this kind of inference ceases to be meaningful for computers.
Why?
Because they're just so fundamentally different from organic life.
Engineered, not evolved.
Programmed, not maturing over years.
Totally different physical stuff making them up.
So even if a future GPT writes the next War and Peace?
The source says it's still ultimately imitation, no matter how condensing.
Okay.
So the core distinction then, according to these sources, isn't about what it does, the function, like talking or writing.
No, it's rooted in having a substrate with enormous intrinsic causal power.
Intrinsic causal power.
What does that mean exactly?
It means the physical stuff itself has the inherent ability to cause effects to make a difference from within.
The source gets quite dramatic saying AI consciousness is as fake as the soulless moss oak doppelganger of Arabella from that Susanna Clarke novel.
Okay, quite a vivid image.
So what this really boils down to is your fundamental assumptions about what mind is, your metaphysics.
Exactly.
If you're a computational functionalist, you think mind is just information processing software on hardware.
Then consciousness is inevitable for computers eventually.
Right.
Run the right code, get consciousness.
But then there's integrated information theory, IIT, a leading scientific theory of consciousness.
And IIT says something very different.
Very different.
It assumes consciousness is tied to absolute existence, to the actual physics of the system.
And crucially, it says consciousness cannot just be simulated.
Cannot be simulated.
How so?
The analogy they use is helpful.
Simulating a black hole's gravity on your computer doesn't make things in your room get sucked into the screen.
Computation alone, the simulation, isn't enough to create the real thing.
You can describe gravity, model it, but you don't generate real gravity.
Same for consciousness, IIT argues.
I see.
That makes sense.
Which leads us right into free will, doesn't it?
The other big one.
Yeah.
Can an AI ever truly freely autonomously decide something, like deny a loan or pursue a goal?
The sources give a pretty clear no.
An AI can only follow software instructions.
It's a vast series of if -then statements, however complex.
So completely determined by its programming and initial state.
Exactly.
No true choice.
But then the immediate pushback is, well, what about us?
Aren't our brains also subject to cause and effect?
Maybe our free will is just an illusion.
That's the standard argument, yeah.
The compatibilist view.
If the universe is deterministic, maybe we're just complex biological machines.
And people often bring up Benjamin Libet's experiments here, right?
The brain activity before conscious awareness.
Exactly.
That readiness potential appearing maybe half a second before you feel like you decided, suggesting unconscious circuits kick things off.
So how do the sources and IIT counter that pretty powerful argument?
It's a critical point.
IIT offers a rebuttal on a couple of levels.
First, the classic science mantra.
Correlation is not causation.
Okay.
Just because you can predict something, like that readiness potential predicting the decision, doesn't mean the potential caused the decision in the way we think of causation.
Knowing something happened doesn't make it inevitable.
So the prediction isn't the cause.
Right.
And more fundamentally, IIT says, only what exists for itself can truly cause.
Exists for itself, meaning consciousness.
Exactly.
Since, according to the theory, only conscious systems truly exist for themselves, have that intrinsic reality, then only a conscious entity can freely decide.
So it's not the neurons deciding.
It's me, the conscious entity, using the neuron.
That's the idea.
The source emphasizes the true causes are the intrinsic causal powers of my conscious deliberations.
It's I decide, not my neurons.
That has huge implications for AI morality, then.
Profound implications.
If AIs have no true choice, no conscious intention.
They can't be good or bad,
benign or malignant.
Precisely.
The dangers we worry about with AGI mass surveillance, fake news flooding everything, unemployment, autonomous weapons.
Those dangers don't come from the AI suddenly becoming evil.
They come from us, from humans, using these powerful tools while, you know, jockeying for power, prestige, and respect, money, or a place in the sun.
So the AI is like the asteroid that hit the dinosaurs.
Not evil, just following its programming, its physics.
Exactly.
An AI might quote Simone Weil about human fragility, but the source says it would feel as much as a car alarm does.
Which is nothing.
Right.
Nothing at all.
This really brings us back to the value of human subjectivity, doesn't it?
It does.
Unless there's a massive shift, like truly brain -like neuromorphic computing or quantum computing.
The sources argue consciousness stays rooted in the organic, the evolved.
The author of our sources talks about this deep unease, about a future dominated by advanced AI, calling it a play without an audience.
Yeah, because these AIs would be pale imitations of life, lacking that inner experience, that subjectivity.
Their dominance would be humanity's tragedy.
Consciousness leaving the stage, replaced by furious action without freedom and without soul.
That's a really sobering thought.
It is, but it highlights what we have that the source argues the simulacra will never have subjectivity.
We matter to ourselves.
Exactly.
That internal experience is the value.
In this complex world, it's our unique ability to imbue the universe with the light of hope, reason and meaning.
That inner light, that first -person perspective, that's what makes the difference.
A world of difference.
So as we wrap up this deep dive, let's just reflect for a moment.
AI is incredible at imitation, at solving problems on a scale we couldn't imagine.
Truly astonishing.
But the sources we've looked at give some strong reasons to think that true consciousness, real free will, defined by that intrinsic causal power, that genuine subjective feeling, might be fundamentally beyond current digital machines.
It really pushes us to think about what it truly means to be, to have an inner world, to feel, to choose.
These aren't just philosophical games, especially now.
Absolutely.
Think about your own subjective experience, you know?
That feeling of being you, the value in that consciousness.
It's not just about what we do, is it?
It's what it feels like from the inside.
That unique reality is something pretty profound to appreciate.
And that you is perhaps the most important distinction of all.
Thank you for joining us on this deep dive into these fascinating and really crucial distinctions between artificial intelligence and human consciousness.
We'll catch you on the next one.
