Reasoning with Robots

As technology has invaded many facets of our lives, I am guessing that all of us experienced the frustration of trying to reason with algorithmic minds. Have you ever raised your voice to a device, asking “Really!?” We might wonder if the application was designed by an unpaid intern, or if the designer ever tried to use it in realistic circumstances. But no amount of frustration will have an effect. The operating space is prescribed and rigid, so that no matter how many times we try, the thing will stubbornly execute the same boneheaded behavior.

Imagine that a self-driving car in a city detects a voluminous plastic bag in its way. It will stop, and say—perhaps silently to itself—”Object.” “Object.” “Object.” “Object.” “Object.” “Object.” I could go all day. No, actually I can’t. But it can, and that’s the point. A really sophisticated version might say: “Bag.” “Bag.” “Bag.” “Bag.” Meanwhile, a human driver might look at the bag, and based on the way it waves in the breeze decide that it’s mostly empty, but just looks big, and is safe to drive over without even slowing down—thus avoiding interminable honks from behind.

Arguing with robots would likely be similarly tedious. No matter what insults you are compelled to fling after reaching your frustration threshold, all you get back is the annoyingly repetitive insult: “Meat bag.” “Meat bag.” “Meat bag.”

Meat bag brains have the advantage of being able to take in broader considerations and weave in context from lived experience. We can decide when algorithmic thinking is useful, and when it has limits. Unfortunately, I buy the argument from Iain McGilchrist that modern culture has increasingly programmed people to be more algorithmic in their thinking—in my view via educational systems, video games, and ubiquitous digital interfaces. I often feel like I’m arguing with robots, but of the meat variety.

Text Substitutions

Most people are probably familiar with text substitution, in some form. It’s when a particular bit of text in a document is replaced throughout with an alternate. In many packages this is carried out via a Find/Replace dialog box. My main use has been in a Unix/vi environment, where the friendly and intuitive command :1,$s/old text/new text/g finds every instance of “old text” and replaces with “new text.” The true nerd will appreciate that the command is compatible with ‘regular expressions’ (an innocent-looking term that conceals a boatload of nerdcrap).

Over the years, I have developed a number of automatic text substitutions for phrases/platitudes I hear people utter. The filter works so that what I hear is converted into my internal version before processing further. This post collects a few such examples, although I’m sure I’ll think of more after the fact.

In each of the cases below, the heading is the spoken phrase, and the bold sentence that follows is my internal translation.

Wasp Wisdom

My patient wasp family on the end of their stick, after completing woodshed reconstruction.

One way to measure the change I’ve undergone in the last several years is via wasps. That’s right: wasps.

It’s as if I woke up one morning realizing that I grew up in a society of human supremacists, that I was one too, and that I no longer want to live that way.

In 2022, I began heating my home by burning firewood—mostly from scavenged trees in my forested area that have blown down. I needed a shelter for drying the wood and hastily constructed a structure mostly out of spare materials on hand. This summer, I decided to gussy it up to last a while. As I began unloading wood from it so I could rebuild it from the ground-up, I found a small nest of paper wasps attached to a stick on top of the pile, just under the roof. It was a smart location for the wasps.

In the past, I would have eliminated the nest, as it interfered with my plans. My biggest concern would have been how to wage war on the wasps without any risk to myself. Growing up, I feared wasps. I suppose I imagined they were after me—which I see now as a form of projection. Mentally, I was at war with wasps, so naturally these enemies would also be at war with me. If they weren’t so dumb, they would ambush me as a preventive offensive.  It is somewhat telling that when I searched on the internet to identify the wasps, a shocking fraction of the search results pointed to sites geared toward exterminating these “pests.”

Now that I am trying to operate as a humble member of the community of life, and to think of wasps as sisters who have been around for a long time and can probably teach me a thing or two, I find that my initial reaction is not one of fear, but of admiration.

The wasps did nothing wrong in choosing their spot. It was a solid choice. My desire to rebuild the shed was outside the parameters of normalcy. So I decided to work around them.

Confessions of a Disillusioned Scientist

AI-generated stranger; I’m not so young/attractive

After a rocket ride through science, I am hanging up the gloves, feeling a little ashamed and embarrassed to have devoted so much of my life to what I now see as a misguided cause that has done more harm than good in this world.

The previous post details my views about the limits of science. In this post, I will focus more on my own reaction as a human participant in the enterprise.

As is so often the case, my trajectory, in hindsight, looks straightforward and linear. Halley’s comet introduced me to the sky in 1985–1986 at age 15–16, quickly leading to my building a 10-inch Newtonian telescope on a German equatorial mount (using plumbing parts from my plumber neighbor). Through this telescope, I saw all nine planets in one night (when there were nine), an individual star (supernova) 36 million light years away, and a quasar 2 billion light years away. I was a physics major at Georgia Tech and spent every-other-quarter at the Naval Research Lab working on optical communications for space. I had my pick of graduate schools, and chose Caltech for its idyllic setting, its relaxed, collaborative atmosphere, and access to “big glass.” Within a few months of starting, I had gone on observing runs to the venerable Palomar 200-inch telescope and the Caltech Submillimeter Observatory on Mauna Kea. What a dream I was living! Meanwhile, I enjoyed many outdoor adventures with fellow grad students, some of whom have become life-long friends.

I did not expect to stay in academia (the statistics were not encouraging to a middling student), and interviewed at a few “industry” jobs while also dipping a toe into “prize” postdoc fellowships and create-your-own postdoc adventures. I picked one from the “adventure” bucket, to start a lunar laser ranging project as a test of general relativity at the University of Washington. Abandoning my graduate expertise in infrared astronomical instrumentation was risky, but I saw this postdoc as a last hurrah in academia, deciding that I might as well have fun. I loved the people I worked with, and savored my time in Seattle. Unintentionally, this gutsy move looked very attractive to faculty search committees, two of which tracked me down based on the reputation of my graduate work and then put me on their short lists after learning of my new direction. One of these led to a tenure-track job at UCSD starting in 2003, where I kept the pedal to the metal on the lunar ranging project. During a 20 year career there, I was never turned down for funding my project, hit all the usual promotion steps at the expected times (tenure then full professor), and felt that I had “made it” by all traditional measures. Having written and reviewed a large number of peer-reviewed papers and served as panel reviewer for NASA and the NSF for far more proposals than I ever wrote, I knew the “game” quite well. I had a versatile set of powerful tools that I could bring to bear on what seemed like almost any problem. Science was, in some ways, the essence of my being, and I found plenty of reward in it—both intrinsically and societally.

So, what happened?

The Intransigence of Now

Everybody has beliefs. Many are so deeply ingrained that we do not even recognize them as such. The most staunch scientist—who spurns belief in Santa Claus or God—still operates on a metaphysical foundation of beliefs about how the world works: e.g., that the scientific method is the only valid path to truth, and that unproven conjectures have little worth—and unprovable ones even less—even if quite possibly correct (and important). For instance, science can probably never tell us if animals experience emotions the way humans do, but isn’t it obvious by non-scientific interactions? Maybe some animals experience a sense of awe for natural phenomena, or notice the stars and wonder, or are more aware of their own mortality than we could ever know. Plants “scream” when attacked; will science ever deliver an understanding of what it is like to be a tree? How could it?

But I digress, already. This post is not about the narrow, literalist, and almost certainly incomplete metaphysics of science, but about the stubbornness of brains. People have a very hard time getting rid of some notions, or accepting something that runs counter to their assumptions. One might even suspect some “hard” wiring at play! Hey wait—people’s predispositions, personalities, and beliefs must indeed map to real neural connections in their brains (where else: we don’t use cloud storage!). Changing minds means down-weighting or destroying some connections and making new ones: not easy. Incomplete attempts often “repair” themselves back to something close to the original state, as beliefs are woven into so many offshoots as to be difficult to eradicate fully.

But neither is this a post about brain functions. Come on, Murphy, get it together! What this post is about is how intransigent people are, in general. After a few familiar examples, we’ll turn an important case: people have a very hard time seeing how unusual and temporary this moment is, it having lasted all their lives and more. The claim that most humans don’t appreciate the obvious temporary nature of modernity might seem as dismissive as the claim that animals don’t appreciate their own mortality. Yet some can, and that’s very important.

The Ride of Our Lives

How much time do we spend fretting over the course we take as a human species? Granted, perhaps too few are focused on ultimate success, which I define as long-term sustainable living as a subordinate partner to all of life on Planet Earth. Even for those who do concern themselves with the intermediate and far future, attention tends to focus on what adjustments we can make to steer a safer course. Yet, when have we ever truly steered our path as a species? Are we actually in control at all? I’ll argue that we’ve never really been in the driver’s seat on the decisions that have mattered most. Our path has been more like an amusement park ride equipped with an ornamental steering wheel, giving the adorable tykes an intoxicating but illusory sense of control.

The central idea is that any development conferring a short-term competitive advantage will come to dominate the landscape, so that failure to adopt it means losing the race and dropping out of the future. It’s a meta-evolution selecting for something other than our best interests. And it’s winning, as it must.

Human Exceptionalism

From Pixabay/Activedia

For almost two decades now, I have been on a journey to understand what comes next in the grand human enterprise. I started out in a mindset superficially similar to that of most people I encounter—assuming that we would innovate our way into a future that became ever better: less poverty and hunger; greater conveniences; a probable space future—fingers crossed.

But the more I dug into the details, the more concerned I became that such a grand vision is an illusion built on top of a highly anomalous period in human history when we over-exploited finite resources on Earth in a one-time bonanza—using those resources to access remaining resources ever faster in an accelerating cycle. I constantly sought reassurance as to what I had wrong about this picture, but found little solace. Those who tried to ease my mind spoke in vague praise of human capabilities and pointed to the arc of history as a reliable pattern by which to understand the future. I did not get the impression that they had confronted my specific concerns and had a blueprint for how to navigate past the pile-up of global-scale problems and irreversible consumption of our inheritance.

Lately, as I meet other academics (via PLAN) who have come to similar conclusions (sober, deep, and careful thinkers, I find), a frequent question that arises is: how can something that seems so obvious to us be dismissed by so many others? What are we missing? Or what are they missing? Why is it so hard to reach common ground? Where is the disconnect?

An answer—or at least a partial one—is beginning to resolve itself in my head. Previously, I tended to focus on growth and ecological overshoot as the most important “upstream” factors impacting our complex civilization on our road to an uncertain future, while issues like climate change and political/social considerations are downstream effects (symptoms) that will not get solved without first addressing root causes (the underlying disease). But maybe I have stumbled onto something even more foundational—the headwaters (pathogen), if you will—and am starting to pinpoint why our peril is so hard to grasp.

Caught Up in Complexity

From analogicus, via Pixabay

Readers of this blog will know that I have come to some big-picture conclusions about success and failure that are unsettling. I don’t like them myself. Not only do they create an inner sadness about where I think the human endeavor is heading, but they result in a sort of isolation that I would rather not suffer—introvert though I am. Among other academics at my institution, it is rare for me to find kindred spirits, even among groups self-selected to care about environmental issues. Most don’t seem to see very far beyond climate change in the lineup of existential threats, increasingly focusing on inequities within the human population that stem from climate and environmental disturbances. I am glad that climate change awareness is high (a genuine threat), but even if climate change had never arisen, I think we would still be in grave trouble from the more fundamental flaws in our explosive approach to living on Earth.

This is a large part of the impetus behind PLAN, which I announced in the last post. Already, I am gratified that people joining the network from vastly different fields and experiences have formed similar conclusions at the highest level. So I’m not crazy, unless we all are. In any case, I am less lonely. [I will say that crazy is usually easy to spot in conversation: a little too insistent/enthusiastic/one-track. The PLAN folks feel really solid, broad, and even perhaps subdued to me: not the type you want to back away from at a party.]

But I still try to understand why so few of my colleagues have reached similar conclusions. The easy answer is that I’m just plain wrong. But believe me, I have tormented myself to try to discover the missing piece and go back to being a happy human bumping along in this race to who-knows-where. It’s not that my unconcerned colleagues have thought more deeply about the issues and can help a rookie out, in my experience.

In this post, I venture some guesses about the disconnect—some of which may even be on target. I will loosely frame the discussion in the context of academia, but much of the logic  also applies beyond this scope. The basic idea is: complexity makes it hard to differentiate between  real and artificial worlds.

Credibility from Apparent Hypocrisy

Flip the script! Image by Gerhard G. from Pixabay

Purveyors of unpopular messages are often scrutinized for any inconsistent, seemingly hypocritical behavior that might give lie to their preachings and be used to discredit the unwelcome perspective. A famous example is Al Gore’s heavy air travel schedule to spread the word and take action against climate change, resulting in an enormous CO2 footprint. If we all behaved that way, the very problem at hand would be substantially exacerbated.

Such accusations either knowingly or pathetically miss the obvious point that the net effect of Al Gore’s efforts may be positive owing to the simple idea of a lever: a little expenditure here can counteract vast expenditures elsewhere for an overall gain on the problem. For many, the glaring superficial contradiction is enough ammunition to discredit the entire enterprise.

But identifying possible hypocrisy in those who warn of future perils, as I have done, has a dark edge: if even those cognizant individuals cannot get away from behaviors they know to be damaging, doesn’t that only amplify the severity of the warning?

To What End?

Image by naturfreund_pics from Pixabay

Recent reflections on the long-term trajectory of the human enterprise have somewhat transformed the way I look at most activities. Specifically, I refer to the dual realizations that on 10,000 year timescales ultimate success is effectively synonymous with true sustainability, and that the human race stands in blatant breach of contract with evolution and ecosystem parameters—fueled by a mad grab of one-time finite resources. The net effect is that most human activities today promote ultimate failure rather than ultimate success.

As such, when evaluating a proposed or ongoing effort, I ask myself the question:

To what end?

This post will examine some of the activities of current society, and evaluate how much sense they make in the context of a post-party future.
