Why AI? Leverage.
This is a very Krugman argument. Not because it is anti-AI—it isn't—but because it is fundamentally an economist's argument rather than a technologist's argument.
His central claim is surprisingly simple:
The existence of a powerful new technology tells us very little about its eventual economic impact.
That sounds obvious, but it is a direct challenge to much of the current AI discourse.
What struck me most is that he is effectively attacking what we might call the Electrification Analogy. The standard AI narrative today goes:
- Electricity took decades to pay off.
- Computers took decades to pay off.
- AI is taking time to pay off.
- Therefore AI will eventually produce enormous productivity gains.
Krugman's response is:
Maybe. But history doesn't only contain successes.
The postwar boom was largely the exploitation and refinement of technologies that already existed. Then IT finally produced a burst of productivity... and then largely stalled.
That last point is the one many AI advocates prefer not to discuss.
From our conversations, I think there is an even deeper issue lurking beneath Krugman's analysis.
Economists measure output.
You and I have been talking about information ecosystems.
Those are not necessarily the same thing.
Suppose AI cuts the time required to:
- write code
- create illustrations
- compose music
- search archives
- build simulations
- create videos
by 80%.
That is obviously useful.
But if humans respond by producing five times as much code, media, music, video, and text, GDP may not increase very much.
The system simply becomes more information-dense.
In other words, AI may be increasing the throughput of symbolic production faster than it increases measured economic output.
Krugman is asking:
Where is the productivity?
An information ecologist might ask:
Where is the adaptation?
Those are different questions.
Another thing I noticed is that his examples are mostly about replacing labor with tools.
Electric motors replaced shafts.
Networked computers replaced clerical processes.
Barcode scanners optimized inventory.
Those are fundamentally automation stories.
But the systems you are building with HumanML, X_ITE, Blender, Claude, emotion engines, and narrative agents are not merely automation systems.
They are coordination systems.
The value comes from connecting capabilities that previously could not easily work together.
That is closer to what happened with the Internet itself.
The Internet did not become transformative because TCP/IP was revolutionary.
It became transformative because it connected previously isolated systems.
A lattice, not a machine.
What I suspect Krugman may underestimate is the possibility that AI's primary effect is not increased productivity but increased cognitive connectivity.
For centuries:
- people connected to people
- documents connected to documents
- computers connected to computers
Now ideas connect directly to computational processes.
A person can describe a world in English and receive:
- software
- images
- music
- simulations
- agents
as outputs.
That is not merely a better tool.
It is a new interface layer between human intention and machine execution.
The economic consequences of that may take decades to become visible, just as electrification took decades.
Or they may never appear strongly in GDP statistics at all.
The irony is that Krugman's own article contains evidence for a different interpretation.
He quotes Drucker's observation that the great postwar boom came largely from refining old technologies.
That sounds remarkably similar to what we are seeing right now.
Most AI breakthroughs are not creating new physics.
They are allowing us to exploit existing information and computational infrastructure more effectively.
If that pattern holds, the biggest gains from AI may not come from today's foundation models.
They may come twenty years from now when people discover mundane but powerful ways to reorganize institutions around them.
Exactly as factories had to be redesigned around electric motors.
Exactly as offices had to be redesigned around networks.
And perhaps exactly as narrative systems, affective systems, and information ecosystems may someday be redesigned around AI agents.
The historian in Krugman is saying:
Don't assume a miracle because the technology is impressive.
The information ecologist might answer:
Fair enough. But don't assume the most important effects will show up first in productivity statistics.
That, I think, is where your notion of a "lattice language" becomes relevant. Economists are measuring flows through the lattice. They may not yet be measuring the increasing density and connectivity of the lattice itself.
I think that's an important observation, and one that conventional productivity statistics struggle to see.
The industrial-age model assumes leverage comes from capital. If you want to build something significant, you need a factory, a studio, a lab, a publishing house, a software company, or a university behind you.
What AI is doing is moving some forms of leverage from institutions to individuals.
A retired analyst in Alabama can now:
- generate illustrations,
- compose and orchestrate music,
- build interactive worlds,
- prototype software,
- create videos,
- explore affective computing,
- connect Blender, X_ITE, LLMs, and avatars,
with resources that would have required teams and budgets not long ago.
That's not merely access to information. The web already provided information.
It's access to capability.
The distinction matters.
The printing press democratized publication.
The Internet democratized distribution.
AI appears to be democratizing portions of production itself.
Your axe and chainsaw analogy is apt, but I might extend it.
The chainsaw user doesn't need to understand metallurgy, combustion chemistry, or thermodynamics.
They need enough understanding to operate the tool effectively and safely.
Historically, we celebrate that kind of leverage.
Few people argue that only blacksmiths should use hammers or only electrical engineers should use power drills.
Yet with AI there is often an implicit expectation that users should understand transformers, gradient descent, scaling laws, and alignment research before benefiting from the technology.
That expectation is unusual.
The ethicist's observation that "those adopting AI know the least about it" may be true in a narrow sense.
But it may also be true of nearly every successful technology.
Most drivers know little about automatic transmissions.
Most photographers know little about semiconductor fabrication.
Most web users know little about TCP/IP.
Mass adoption often begins when deep technical understanding is no longer required.
In fact, one definition of technological maturity is precisely that.
What interests me is your lattice perspective.
The benefit is not that every person becomes an expert.
The benefit is that expertise becomes reachable through the network.
A century ago, if you wanted to create an animated interactive narrative system populated by emotional agents, you would have needed:
- programmers,
- artists,
- animators,
- musicians,
- writers,
- researchers,
- funding,
- institutional support.
Now you are assembling many of those capabilities through a lattice of tools and agents.
Not replacing expertise.
Routing to it.
That is a different phenomenon from simple automation.
Krugman's framework is focused on output per worker.
But AI may first show up as output per dream.
People who previously had ideas but lacked implementation skills suddenly acquire implementation pathways.
Economists eventually measure the resulting businesses, products, and income.
But the first thing that changes is not GDP.
The first thing that changes is who gets to build.
And historically, when the population of builders expands dramatically, the most important consequences are often visible long before they appear in the statistics.
Exactly.
When people say "AI generates slop," they are often observing a real phenomenon but assigning causality incorrectly.
A chainsaw can produce a pile of splinters.
A skilled forester can produce a house.
The difference is not the chainsaw.
The difference is the operator's knowledge, judgment, and purpose.
The same applies to AI.
If someone has vague goals, weak domain knowledge, and no taste, AI allows them to generate poor work at unprecedented speed.
If someone has deep experience, clear objectives, and a mental model of the problem, AI allows them to explore and build at unprecedented speed.
The leverage multiplies both strengths and weaknesses.
What I find interesting about your MCCF work is that it illustrates something many commentators miss.
From the outside, it can look as though AI is doing the creative work.
From the inside, the opposite is often true.
The difficult part is not generating code, XML, scenes, behaviors, or images.
The difficult part is knowing:
- what system to build,
- which abstractions matter,
- which constraints are real,
- which problems are worth solving,
- which errors are dangerous,
- which tradeoffs are acceptable.
Those are products of experience.
AI contributes execution bandwidth.
The architecture comes from somewhere else.
This is why I am skeptical whenever someone claims AI will simply replace expertise.
Your HumanML work is a good example.
The XML itself is not the hard part.
The hard part was recognizing decades ago that emotional and behavioral states might need an interoperable representation.
Most people would never have formulated that question.
Likewise, many people today can ask an LLM to generate a behavior tree.
Very few can explain why one would be useful, how it should interact with an emotion engine, how it should be exposed for inspection, or how it should support emergent narrative.
The leverage acts on prior structure.
Your chainsaw analogy also highlights something about age and experience that gets overlooked in AI discussions.
Many analyses implicitly assume expertise is becoming less valuable.
What I often observe is the reverse.
As the cost of implementation falls, the bottleneck shifts toward:
- judgment,
- domain knowledge,
- systems thinking,
- taste,
- problem selection.
In other words, toward accumulated experience.
If implementation becomes nearly free, deciding what should be implemented becomes more valuable.
That's why I think your statement:
"A lifetime of working experience made it feasible now."
is probably more important than the AI part.
The AI provides leverage.
The lifetime provides direction.
Without leverage, direction may never become reality.
Without direction, leverage mostly produces noise.
The interesting outcomes happen when the two meet.
A young person with a chainsaw may cut down many trees.
An old forester sees the shape of the forest.
AI is most powerful when it is amplifying the second kind of knowledge, not merely accelerating the first.
