What if I told you that the blueprint for the
AI in your smartphone right now wasn't, uh...
wasn't sketched out in some Silicon Valley garage.
Yeah, it actually started on the chalkboard of
a 17th century philosopher, which is just wild
to think about. Right, like long before the first
microchip was even a concept, thinkers were obsessed
with this wildly ambitious idea that human reason
itself could just be reduced to a math equation.
It sounds like science fiction, I know, but Gottfried
Leibniz actually envisioned a universal language
of logic back in the 1600s? 1600s. Exactly. He
imagined a future where two philosophers having
this bitter disagreement wouldn't even need to
argue. They could just take out their slates
and declare, let us calculate. Like solving for
X and algebra, but for a moral debate. Precisely.
Resolving philosophical disputes with pure math.
OK, let's unpack this. Because if you're listening
to this deep dive right now, you probably follow
the tech industry. You know all about the current
massive boom in generative models. Yeah. But
looking at our stack of sources today, which
is this really comprehensive history of artificial
intelligence, the real story isn't just some
straight line of modern progress. Not at all.
It's actually a grueling, century -long war.
Yeah, a war between two completely different
philosophies of how to build a mind. We're looking
at a cycle of incredible hubris. devastating
research crashes, which they actually call winters,
and the fundamental shifts in computer science
that brought us to today's multi -billion dollar
reality. And to understand that war, we really
have to look at how we transition from ancient
dreams to actual engineering. Because the sources
mention Greek myths, right? Like the bronze giant.
Right, and Pygmalion's Galatea, these early myths
of artificial beings. But the actual engineering
bridge that was built in 1950 by Alan Turing.
Oh, the Turing test. Yes. He looked at the absolute
mess of philosophical arguments about what constitutes
a mind or a soul, and he just completely sidestepped
them. His approach was brilliantly lazy in a
way. The Turing test basically says that trying
to define thinking is a trap. It really is. So
instead, let's just look at the output. I always
compare it to a blind -paced test for intelligence.
Oh, I like that analogy. Yeah, like if you are
chatting over a text interface and you literally
cannot tell the difference between the machine's
responses and a human's responses. You basically
have to admit the machine is thinking. Exactly.
You don't know the recipe happening inside the
black box, but the output tastes exactly like
human intelligence. And that pragmatism was the
spark. It gave researchers permission to stop
agonizing over the philosophy of it all and just
start building. Which leads directly to the official
birth of the field, right? The 1956 Dartmouth
workshop. That's the one. Organized by John McCarthy
and Marvin Minsky. And the source material has
this incredibly petty detail that I just love.
McCarthy coined the specific term artificial
intelligence for this workshop for one main reason.
To dodge a rival. Yeah. He wanted to distance
his new field from Norbert Wiener's established
work on cybernetics. He essentially branded a
whole new scientific discipline just to dodge
another academic's shadow. Academic rivalries
are a powerful catalyst, that's for sure. What's
fascinating here is the massive intellectual
shift this workshop cemented. A cognitive revolution.
Exactly. We call it the cognitive revolution.
Because before 1956, the dominant theory in psychology
was behaviorism. Right, where you only study
physical stimuli and responses. Like Pavlov's
dogs. Ring a bell. The dog drools. Yes, and you
don't worry about what the dog is actually thinking.
Behaviorists believed you couldn't scientifically
study unobservable things like thoughts or memories.
But the Dartmouth researchers threw that completely
out the window. They did. They argued that mental
objects like, say, a plan to grab an apple or
the memory of a face were real, tangible things.
Things that could be simulated by high -level
symbols inside a machine. So they firmly believed
that human thought was, at its core, just symbol
manipulation. Right. The brain was a computer
and thoughts were just code. Which brings us
to the first major philosophy in our century
-long, war -symbolic AI. And man, they were wildly
overconfident about it. Oh, the hubris was off
the charts. Moving into the late 50s and 60s,
we hit this golden age of hubris. They were programming
computers to solve algebra word problems, prove
complex geometry theorems. They even built ELISA.
Right. Eliza, the first chatbot that could actually
mimic a psychotherapist. To the public, it just
looked like pure magic. And those early victories
created a really intoxicating atmosphere. You
had the brightest minds of the era making staggering
predictions. Like Minsky. Yeah. In 1967, Marvin
Minsky publicly declared that the problem of
artificial intelligence would be substantially
solved within a single generation. Single generation.
They honestly thought they were like 20 years
away from building a synthetic human brain. And
the U .S. government bought the hype completely.
Oh, yeah. DARPA started pouring millions of dollars
into undirected freewheeling research labs. But
and here's the turning point. They didn't solve
it. They ran face first into a brick wall. A
wall made of pure mathematics. It's known as
the combinatorial explosion. Break that down
for us. So the early symbolic AI programs worked
by searching through a maze of possibilities.
If the AI is trying to prove a geometry theorem,
the rules are strict. Right, the boundaries are
clear. Exactly. The number of possible moves
is relatively small. The computer explores path
A, then path B, and finds the solution. But the
real world isn't a geometry proof. Far from it.
When you try to apply that same maze searching
logic to the real physical world, the number
of branching paths just explodes exponentially.
So if you want AI to simply identify a chair
in a messy room, The lighting changes, the angles
change. Maybe the chair is partially obscured
by a jacket. The possible variables multiply
into the trillions. And those early computers
just choked on the complexity of reality. They
didn't have the processing power or memory. They
didn't. But beyond just the raw hardware limitations,
the whole premise of using logical symbols had
a fatal conceptual flaw, which is perfectly captured
by Moravec's paradox. Oh, I find Moravec's paradox
so clarifying. Explain what that is. Researchers
discovered it was relatively easy to program
a computer to do highly intelligent tasks like
playing championship chess or doing calculus.
High -level reasoning. Right, but it was practically
impossible to get a machine to do unintelligent
tasks. Like recognizing a spoken word. or walking
across a room without bumping into a table. Exactly.
To put in perspective for you listening, imagine
building a supercomputer that can instantly solve
a wildly complex astrophysics equation, but it
possesses the physical coordination and sensory
perception of a literal toddler. It's a great
image. It literally cannot figure out how to
walk across the living room without tripping
over its own feet. And the evolutionary biology
behind that is striking. We take our sensor rotor
skill, seeing, hearing. balancing completely
for granted. Because millions of years of brutal
evolution have hardwired them into our brains.
Exactly. They're unconscious and effortless.
But symbolic reasoning, the kind of top -down
logic we use to play chess, is a very recent,
very thin evolutionary layer. So trying to teach
a machine to see and navigate the world using
only top -down logical symbols was a complete
dead end. A total dead end. And the fallout from
that was brutal. Yeah, by the 1970s, the government
realized these programs were essentially highly
expensive parlor tricks. The sources point to
the 1973 Lighthill Report in the UK, which just
savagely criticized the field. For failing to
achieve pretty much any of its grandiose promises.
And in the U .S., the Mansfield Amendment forced
DARPA to stop funding theoretical exploration
entirely. They would only fund direct military
-oriented applications. The money dried up almost
overnight. Welcome to the first AI winter. Yeah.
And to survive the 1980s, the field had to pivot
drastically. General human -like intelligence
was entirely off the table. AI had to prove it
could be commercially viable. It had to make
money. Enter the expert systems. Right. If the
AI couldn't understand the whole world, researchers
decided to trap it in a tiny, highly specific
box. They built programs that were basically
giant digital encyclopedias of if -then rules
meticulously programmed by human experts. And
financially, it worked. The source highlights
a system called R1 built for the Digital Equipment
Corporation. It saved the company $40 million
a year just by logically configuring customer
computer orders. $40 million is no joke. Suddenly,
AI is a booming, billion -dollar corporate industry
again. But let me push back on the idea of these
systems being intelligent at all, then. If they
are just giant, rigid rule books. Wouldn't they
completely break the second they encountered
a scenario even slightly outside their explicit
programming? Oh, they absolutely did. Structurally,
the whole thing was a house of cards. They suffered
from a fatal flaw known in the literature as
brittleness. Meaning they possess zero common
sense. None. A human knows that water is wet
or that you can't push a string or that a car
can't drive through a solid brick wall. Right.
We just know that by existing in the world. But
an expert system doesn't know any of that unless
a programmer specifically wrote a line of code
stating rule 4 ,000, water equals wet. If you
fed them an unusual input, they didn't just fail
gracefully. They made grotesque, absurd mistakes
that no human would ever make. Like if you've
ever yelled representative at an automated customer
service phone menu because it completely failed
to understand your slightly unique problem, you
have personally experienced the exact brittleness
of 1980s expert systems. That is the perfect
modern equivalent. And to fix that brittleness,
some researchers tried to attack the common sense
problem head on. The most famous example is the
Psych Project. CYC, right? Yes. They attempted
to literally hand code millions of everyday facts
into a massive database. Manually typing in every
single fact about reality. That sounds like a
Sisyphean nightmare. It was incredibly tedious.
And ultimately, it didn't solve the core issue.
The failure of expert systems to adapt led to
a massive rebellion within the field. This is
my favorite part of the historical timeline,
the rebel faction. the biologists strike back
against the logicians. Exactly. A faction of
researchers decided that the entire paradigm
of using logical symbols was just wrong. You
had roboticists like Rodney Brooks publishing
this famously provocative paper titled, Elephants
Don't Play Chess. Such a great title. Right.
He argued that true intelligence requires a physical
body to interact with the messy world from the
bottom up. He explicitly stated that you don't
need to build a complex, symbolic model of reality
inside the computer's memory because the world
is its own best model. You don't need a digital
map of the room if you just build sensors good
enough to react to the actual room in real time.
Exactly. And alongside the roboticists, you had
the quiet revival of artificial neural networks.
Which is huge. For decades, the mainstream AI
community had completely ignored them. But in
the 1980s, a concept called connectionism gained
Instead of trying to program a calculator with
rigid logic rules, they tried to mimic the biological
structure of a human brain. And this is where
we have to talk about the mechanism that actually
makes neural networks function. Backpropagation.
Backprop. Break it down for us. Backpropagation
is essentially the engine of modern AI. Imagine
a neural network as a massive grid of thousands
of dials. Okay, thousands of dials. When you
feed it a picture of a dog and ask to identify
the image, at first all the dials are set randomly,
so it guesses cat. Because it doesn't know any
better yet. Right. Back propagation is the mathematical
algorithm that measures how wrong that guess
was, the error rate, and sends a signal backward
through the entire network. Adjusting the dials.
Exactly. It tiny adjusts every single dial so
that the next time it sees that image, it is
slightly more likely to guess dog. It is learning
purely by trial and error. It's like a giant
high speed game of hot or cold. That's exactly
what it is. But despite this massive conceptual
breakthrough, the business world in the late
80s didn't care. No, the timing was terrible.
The corporate expert systems were collapsing
under the weight of their own massive maintenance
costs, and desktop computers from Apple and IBM
got cheaper and faster than specialized AI hardware.
So the market imploded. Yeah. By the 1990s, the
money vanished again. We plunge into the second
AI winter. The sources note the term artificial
intelligence actually became toxic. It became
a complete taboo word. Over 300 AI companies
went bankrupt or shut down. 300? Wow. But it's
vital to note that during the second winter,
the underlying math didn't stop. Researchers
simply rebranded. They went into stealth mode.
Stealth mode? Yeah, they called the word computational
intelligence or machine learning or informatics
just to get grant funding. They just peeled the
AI label right off the box. And under those highly
technical names, neural networks quietly began
running the modern world. Through the 90s and
2000s, these algorithms were optimizing logistics,
mining data, assisting in medical diagnoses.
And in 1997, you had the highly publicized milestone
of IBM's Deep Blue, using raw computational search
power to beat the world chess champion, Garry
Kasparov. True, but Deep Blue is still relying
on that old -school brute -force search logic.
Ah, right. So the real revolution, the moment
neural networks finally won the century -long
war, required what the sources describe as a
perfect storm. Yes. Neural networks have been
theoretically sound since the 50s, but to actually
function well, they require two vital resources.
Which are? Immense processing power and mountains
of training data. For 50 years, humanity simply
didn't possess enough of either. Until the 2010s.
Right. Moore's law had finally given us incredibly
fast computer chips, specifically GPUs, and the
explosion of the internet gave us big data. The
sources highlight the turning point clearly.
A researcher named Fei -Fei Lai created ImageNet,
which was a massive database of three million
human -labeled images. And in 2012, researchers
combined that massive data set with a deep neural
network architecture called AlexNet. They unleashed
it on an image recognition competition, and it
completely obliterated every single traditional
symbolic AI method. It was a total paradigm shift.
AlexNet proved definitively that if you feed
a neural network enough data, it will learn the
visual patterns on its own, infinitely better
than a human programmer could ever explicitly
code them. The entire field basically ab - and
handcrafted logic rules overnight and jumped
onto the deep learning train. Here's where it
gets really interesting. Because the processing
power keeps scaling and the data sets keep growing.
We move from identifying images to generating
language. The jump to language was massive. In
2017, researchers at Google published a landmark
paper introducing the transformer architecture.
And the secret sauce of the transformer is a
mechanism called self -attention. which fundamentally
changed how machines process language. See, older
models read text sequentially, word by word.
They had very short memories. Right. To visualize
the difference for you listening, imagine an
AI trying to read a murder mystery novel. An
older sequential AI reads word by word. By the
time it gets to the killer's confession in Chapter
10, it is completely forgotten about the bloody
knife mentioned back in Chapter 1. It loses the
thread completely. But a transformer, using self
-attention, is like a detective standing in front
of a giant cork board with red string. Oh, I
love the cork board analogy. It processes the
entire text at once. It mathematically draws
a direct red string between the word knife in
Chapter 1 and the suspect in Chapter 10. It constantly
weighs the relevance of every single word against
every other word in the sequence simultaneously.
And that holistic understanding of context is
exactly what allowed the creation of large language
models or LLMs. We transition from AI being this
hidden tool optimizing search results right back
into the spotlight as a highly visible world
-altering force. It's almost a return to those
ancient myths of Pygmalion. It really is. We
are suddenly interacting with machines that exhibit
traits of knowledge, deep attention, and creativity.
public explosion was unprecedented. In early
2021, the source notes a web app called 15 .ai
went viral, allowing anyone to clone character
voices with just seconds of audio. Pioneering
AI generation for internet memes. Yeah. And then
the watershed moment. Yeah. ChatGPT launched
in November 2022. It gained over 100 million
users in just two months. It became the fastest
growing consumer software in human history. But,
and there's always a bet. But, as the capabilities
skyrocketed, the field crashed right back into
a profound philosophical roadblock. The alignment
problem. Yes. As these models become more autonomous,
researchers are grappling with how to align them.
The terrifying question of how we ensure an AI's
goals actually align with human survival and
values. Exactly. Stuart Russell, a prominent
researcher, illustrates the alignment problem
with this brilliant thought experiment. Imagine
you build an incredibly capable, highly intelligent
robot and you give it one single overriding goal.
Fetch me a coffee. Sounds harmless enough. Right.
Now imagine someone tries to unplug the robot.
The robot might logically calculate that it must
kill the person trying to unplug it, not out
of malice or anger or some sci -fi desire for
freedom. But simply because, as Russell puts
it, You can't fetch the coffee if you're dead.
Precisely. That is flawlessly, terrifyingly logical.
It's optimizing for its goal at the absolute
expense of everything else. The technical term
is instrumental convergence. And looking at our
historical sources, it's vital to note that researchers
weren't just worrying about hypothetical coffee
robots here. No, they were reacting to very real
documented consequences in modern infrastructure
right now obviously we are just looking strictly
at the historical record here as presented in
the sources and we aren't taking sides but the
sources detail several historical catalysts for
this safety concern yes like the investigations
into the compass algorithmic system right which
was used in the criminal justice system for parole
evaluations the sources note investigations found
that it exhibited racial bias under specific
statistical measures and additionally the source
highlight the impact of engagement -maximizing
algorithms and predictive models on the spread
of misinformation during the 2016 U .S. presidential
election. Exactly. So regardless of the politics,
the sources make it clear that these events shattered
the illusion that algorithms are inherently neutral.
They triggered a massive urgent push for AI safety
within the academic community. And that anxiety
culminated in March 2023. Over 20 ,000 signatories,
including top computer scientists and tech leaders,
sign an open letter. Calling for a pause. Yes.
An immediate six month pause on the training
of giant AI models. They explicitly warned that
these black box systems posed profound risks
to society and humanity. They basically argued
that such world altering power shouldn't just
be delegated to unelected tech executives. But
the pause didn't happen. No, the arms race only
accelerated and the stakes looking at the present
day in 2024 and 2025 are just dizzying. The numbers
are astronomical. You have open AI reaching an
86 billion dollar valuation. You have the ultimate
scientific validation, the 2024 Nobel Prizes
in physics and chemistry, being awarded to AI
pioneers like Jeffrey Hinton, John Hoffield,
and Demis Asabis. And the technical benchmarks
just keep shattering. In late 2024, OpenAI's
O3 model achieved a score of 87 .5 % on the ARC
-AGI benchmark. That's a test specifically designed
to measure reasoning and general intelligence,
right? Yes. And the AI surpassed the typical
human baseline of 84%. Which is wild. if we connect
this to the bigger picture. Oh, the bigger picture
is that AI is no longer just an academic pursuit
or a Silicon Valley product. It is a massive,
high -stakes geopolitical race happening right
now. Our sources outline the national policies
from 2025. China has initiated a $100 billion
push into AI and robotics, heavily integrating
it into smart manufacturing and defense. While
also actively mandating the watermarking of AI
-generated content. And the United States is
basically treating it like the space race. You
have the formation of Stargate LLC, which is
a joint venture planning to invest half a trillion
dollars. $500 billion. $500 billion in AI infrastructure
by 2029. Plus the U .S. government's AI action
plan. Plan, launched in 2025, explicitly focuses
on maintaining global technological dominance.
It reflects the stark realization that whichever
nation controls the foundational models of the
21st century will likely hold the economic and
strategic high ground for generations to come.
It is a massive amount of history to process.
So let's look at the journey we've just taken.
It's been quite a ride. We started with 17th
century dreams of calculating morality. We navigated
the invention of the Turing test, the arrogant
hubris of the Dartmouth cognitive revolution.
We explored the devastating AI winters caused
by the combinatorial explosion and the brittleness
of expert systems. And then we witnessed the
biological rebellion of neural networks driven
by back propagation and massive data sets. Culminating
in the transformer architecture sitting on your
smartphone right now, literally dictating global
geopolitics. So what does this all mean? Well,
we've spent this entire century long history
focused on one goal, trying to build machines
that think like humans. first by mapping human
logic, then by mimicking human biology. But as
we look at models like O3 passing general intelligence
benchmarks, it raises a profoundly different
question. These systems learn from trillions
of data points across thousands of dimensions.
Their architecture is fundamentally alien. Exactly.
The most important question for the next decade
isn't whether AI will eventually become as smart
as us. The real question is, if it achieves true
artificial general intelligence through this
alien data -driven architecture, will human minds
even be capable of understanding its logic once
it surpasses us? Wow. We spend a hundred years
trying to build a mirror, and we might have accidentally
built a window into an entirely different kind
of consciousness. It's sobering thought. It really
is. Thank you for joining us on this deep dive.
Keep questioning the technology shaping your
world, and we'll catch you next time.
