Ironic Consequences and Universal Engineering.

Humans seem to present a peculiar evolutionary irony. We are the animal capable of growing extraordinarily long facial hair, but we also are the animal that invented shaving. That raises an intriguing possibility: the ability to remove facial hair may have helped remove any disadvantage associated with excessive facial-hair growth.

Shaving didn’t cause genes for long beards. Rather, once humans could cut their beards, excessive growth became less of an evolutionary liability. A cultural invention potentially changed the environment in which biological characteristics were selected.

That suggested a much broader phenomenon. The solution changes the problem.

Humans repeatedly invent ways to overcome natural constraints. But once we overcome a constraint, the solution itself becomes part of the environment. We then change—biologically, culturally, behaviorally, or structurally—in response to the new environment we ourselves created.

Clothing and housing allow us to survive with relatively little protective body hair. So those born with scant hair no longer perished. They produced children without much hair.

Eyeglasses allow people with poor eyesight to function and reproduce successfully. Medicine allows people to survive and reproduce under conditions that otherwise might have killed them.

Tools reduce the survival advantage of physical strength. Agriculture produces plants and animals increasingly dependent upon human intervention. Domesticated woolly sheep survive because humans select and protect animals whose excessive wool would otherwise be a hindrance. 

The same phenomenon appears outside biological evolution. Suppressed small forest fires and fuel accumulate, potentially contributing to larger fires later. Build levees to protect floodplains, and people build more extensively behind the levees; when the levees fail, the cost is greater.

Build a wall to protect the people inside, and the same wall that prevents others from entering prevents those inside from leaving.

Create weapons for defense, and you simultaneously create weapons for offense.

Create government to protect individual lives and freedoms, and you create an institution possessing the power and motivation to restrict those same freedoms.

These aren’t adequately described merely as unintended consequences. There is something more interesting about them.

Ironic Consequences.

The solution alters the system so that the conditions confronting the solution itself change. Sometimes the invention that frees us from a constraint ultimately becomes a new constraint. We become dependent upon the thing that liberated us. That leads to what always seems to be the hardest question—not “What?” or “How?” but “Why?”

Why are Ironic Consequences so Common?

It is tempting to imagine that nature somehow “resists” our interventions—that there is a natural order which, when disturbed, attempts to restore itself. But that introduces exactly the sort of anthropomorphism we must avoid. 

Nature doesn’t resist. Systems respond. Every system we encounter already embodies an enormous history. An organism, forest, river, society, government, climate, or ecosystem consists of innumerable interacting parts, each one having relationships that are consequences of everything that previously happened to them.

Then humans intervene. We tend to imagine the intervention simply as Single Problem —> Solution. But the universe doesn’t contain isolated problems.

When a solution enters an existing system, every component capable of interacting with the change responds according to its own structure, constraints, and history. Those responses alter other conditions and become new stimuli. Those produce still more responses.

Thus, every solution becomes a new stimulus to the system it changes. That may be the fundamental source of Ironic Consequences. We plan the one response we want and the universe supplies all the other responses.

The Boulder and the Twig

This doesn’t mean our interventions are fruitless. A boulder rolling downhill has an enormous, accumulated trajectory. Every bump and pebble affects that trajectory, however slightly, but most don’t reverse it. The boulder continues downhill.

A twig dropped into a raging river will go somewhere. We may predict the general result quite well while being utterly incapable of predicting precisely where the twig first will touch land.

Some future outcomes are heavily weighted. Living organisms eventually die. Rivers flow downhill. Unsupported objects fall. What remains difficult to predict are the supposedly “minor” details—when, where, how, and through precisely what sequence of events.

The important correction is that the boulder never returns to its original trajectory after encountering the pebble. The original trajectory no longer exists. Every second finds the boulder on a slightly different trajectory, incorporating the pebble into its history.

So, what appears to be nature’s inertia isn’t resistance to change. It is the weighting of accumulated history relative to the new stimulus.

That gives us a useful formulation: History does not determine the future. It weights it. Everything that interacts has consequences, and consequences themselves become initiators of further consequences. Every microscopic event becomes important by its weighting. Most tiny effects are overwhelmed by much larger interactions and disappear into the background.

Occasionally, however, a small event enters a system where feedback amplifies it enormously. Give the young Einstein a ball. Suppose he chases it into the street and is killed. An apparently trivial event—giving him a ball — could alter scientific history, military history, political history, and innumerable individual histories.

The ball doesn’t cause all those later events in any simple sense. It changes the history from which all subsequent possibilities emerge. Again, weighting determines whether a tiny perturbation disappears or becomes consequential.

History Cannot be Undone.

This also corrects the idea that nature eventually “snaps back.” Suppose humanity disappeared tomorrow. Forests might reclaim cities. Buildings eventually would collapse. Many obvious traces of civilization would disappear. But Earth never could become the Earth that would have existed had humans never evolved.

We have changed species, genomes, landscapes, atmospheric chemistry, migration patterns, ecosystems, and countless other things. Those changes already have caused still more changes.

Humanity eventually may disappear, but human history cannot unhappen. The future Earth would forever be an Earth whose history included humans. The footprints may disappear, but the effects of making them do not.

And Then There is AI

AI may become the largest example yet of an Ironic Consequence. We create AI because human minds cannot handle certain quantities and complexities of information. AI performs those tasks.

Humans consequently may cease developing or maintaining some of the abilities AI replaces. Then society reorganizes around AI’s availability. Eventually, we created AI because we couldn’t do certain things, and having AI caused us to stop doing many things. Therefore, we could no longer do those things without AI.

The tool created to overcome a limitation could make us increasingly dependent upon the tool. But that same problem provides perhaps the strongest argument for AI.

Human engineering generally solves problems discretely. We identify the individual result we want and try to produce it. But every solution becomes a stimulus to an immensely interconnected system.

A genuinely sophisticated AI might ask not merely, “Will this intervention solve the problem?” but rather. “How will the entire system respond to several interventions?”

“What constraints will disappear? What previously disadvantageous characteristics then may persist? What behaviors will change? What dependencies will develop? What second-order, third-order and n-order consequences will those changes produce?

And what new problems will exist precisely because the original problem successfully was solved?

Universal Engineering

This brings Ironic Consequences directly into the idea of Universal Engineering—identifying and weighting all the variables involved in any solution to a problem.

We never will predict everything. The interacting possibilities are too numerous, and every new response changes the conditions confronting the next event. We will use AI to analyze the consequences of our decisions further into the future.

AI wins at chess because it can “see” the results of more options, further ahead. A weak player thinks, “If I make this move, what happens?” A stronger player thinks, “If I make this move, what can my opponent do, what can I then do, what can my opponent then do…?”

The number of possible futures explodes with every additional move. Humans cope by intuition, experience, pattern recognition, and—very importantly—discarding possibilities. We simply cannot examine everything.

AI can examine vastly more possibilities and carry their consequences further forward before assigning weights to the alternatives. That’s Universal Engineering, writ small.

Suppose instead of a chess move we’re considering a new agricultural practice. The human specialist might ask what it does to crop yield. A better analysis adds cost, water consumption, fertilizer requirements, pests, soil, labor, nutrition, biodiversity, etc.

But every one of those consequences branches again. Change the insects—>changes the birds–>changes seed distribution—>changes vegetation—>changes erosion—>changes waterways…

Very quickly we have a “chessboard” whose number of possible positions is beyond human comprehension.

Now consider constructing the system that will allow permanent human residence on the Moon. How many interrelated variables are there? What are the possible problems, and how will the solutions to those problems affect all the other variables?

Have the “spaceship” people understood all the “living quarters” problems? Have the “living quarters” people understood all the “food” problems, the “psychological” problems, the “sun” problems, the “political” problems, and the countless others? And can every group factor the consequences of its individual solutions into every other group’s problems?

No human mind can manage that multidimensional chessboard. Perhaps no collection of human minds can. But an AI, given vastly more information than any individual human can comprehend, could examine far more of the interactions, follow their consequences further, and continually reweight the possibilities as one proposed solution changes all the others.

The question is not merely whether a solution works. The question is what happens to everything else if it is implemented. That is Universal Engineering. 

And here’s the especially important connection to Ironic Consequences: The chess program doesn’t evaluate a move solely by examining the immediate result. It evaluates the positions that the move makes possible. That’s precisely what we’re saying engineering needs to do.

We shouldn’t ask merely, “Does the levee prevent the flood?” We should ask, “What new world begins to exist if we build a levee or do something else?”

The funding has consequences. The construction project has consequences. The finished product has consequences. People build behind it. Property values change. Wetlands change. Sediment distribution changes. Political expectations change. Maintenance obligations arise. Dependence upon the levee develops. And each of those creates another branching tree.

AI wins at chess not because it knows one perfect move, but because it can examine and weight the consequences of more possible moves further into the future. Universal Engineering applies the same principle to the vastly more complicated chessboard of reality.

And to make things even more appropriate for AI, chess has fixed rules, known pieces, and a defined objective. Reality has none of those conveniences. We don’t even know all the pieces, much less all their interactions.

If the search space is already overwhelming on 64 squares, imagine it when everything potentially communicates with everything else, and each response changes the board. Chess resets the pieces after every game. History never resets the board.

But AI’s Universal Engineering is better at tracking and weighing the variables. AI wins at chess because it can see more options, further ahead. But perhaps AI can allow us to see considerably more of the river before we throw in the twig. 

The underlying principle is that nothing changes alone. Every change enters an already existing web of interactions. Every system responds to the changes. Those responses become new stimuli. Some consequences disappear. Others persist.

Persistence becomes History. History changes the weighting of subsequent possibilities. Then something else happens. History → Event → Response → New History.

And again. Our plans aren’t futile merely because their exact consequences are unpredictable. We constantly alter the weighting of future possibilities, often successfully.

But we should remember that we never change only the thing we intend to change. Perhaps that is the fundamental logic behind Ironic Consequences: Every solution changes the system that made the solution necessary.

And sometimes, by freeing ourselves from an old constraint, we create the conditions that make us dependent on our new freedom.

Oh, and remember that boulder rolling downhill, bouncing over the pebbles? What became of those pebbles? Did just one of them strike another, which struck another, which dislodged a rock, which eventually began a landslide? Or did nothing significant happen at all?

Those are precisely the kinds of consequences humans usually cannot follow. We see the boulder. We don’t see all the pebbles, much less what happens to each of them afterward.

AI’s Universal Engineering would be better able to see the pebbles, too.
