Zager & Evans’ 1969 one-hit-wonder “In the Year 2525” is a bleak little thought experiment set to a fuzz-guitar riff: each verse leaps further into the future, and each leap costs humanity another piece of its agency to some machine, pill, or system. It’s not really about technology. It’s about the moment intention stops being something you execute yourself and becomes something you delegate — and what happens, generation after generation, once delegation becomes the default.
That’s the question this piece chases, era by era. Not “will AI take our jobs” — a much stranger one: at what point does it stop making sense to call the thing being delegated to “software” at all?
I’ve set myself up as a traveler moving through the song’s own timestamps — 2525, 3535, 4545, 5555, 6565, 7510, 8510, 9595, and the wordless coda of “ten thousand years.” At each stop I ask the same six questions: what is this civilization, how does it make new capability, who (or what) plays the developer, what sits between wanting and getting, does “software” still mean anything, and what’s the one implication that would actually surprise someone who’s never left the present. Early stops are extrapolation with the serial numbers still visible — you can trace the line from an AWS re:Invent keynote to what’s described. Later stops are not. I’ll flag the transition as it happens, because the honest answer to “how speculative is this” changes a lot between the first stop and the last.
Mostly plausible extrapolation.
Half a millennium sounds enormous until you remember that the entire history of stored-program computing is one human lifetime deep, and the last five years of it — LLMs going from autocomplete toys to agents that plan, use tools, and hold multi-day projects in working memory — have compressed decades of the previous curve. Run that slope forward, not upward into magic, and 2525 looks like this: natural-language intent has fully closed the loop with executable behavior. Not “the AI writes the code for you” — that’s already banal by 2026 — but that the code as a durable artifact has receded from view the way assembly language receded from view for most of us. What persists is a layered stack of intent, specification, and verification, and what’s rendered into running systems underneath it is regenerated, checked, and discarded continuously, more like a compiler’s intermediate representation than a codebase someone maintains.
Applications, in the old sense, don’t get built; they get specified into existence and then continuously re-derived from the spec, the way a CAD model regenerates a mesh. “Development” becomes the discipline of writing specifications precise enough to be unambiguous and loose enough to leave room for a system to make good judgment calls — closer to contract law and formal methods than to typing for-loops. The people who do this are still recognizably engineers, but their artifact is the boundary of intent, not the implementation inside it.
The developer’s role hasn’t vanished, it’s inverted: instead of being the one who knows how to make the machine do a thing, they’re the one who knows how to ask precisely enough and, critically, how to catch the case where the system did exactly what was asked and that turns out to have been the wrong thing. Verification and adversarial red-teaming — figuring out where a spec has a gap a capable system will happily drive a truck through — is the highest-value skill left, because generation is nearly free and correctness isn’t.
Software is still meaningful here — barely. It’s just moved up a layer of abstraction, the way “software” as a concept survived the move from punch cards to high-level languages. The surprising implication: businesses stop having “engineering teams” as a distinct headcount line and start having “intent quality” as a distinct discipline, the same way “data quality” became its own function once data stopped being scarce. The scarce resource isn’t compute or code anymore. It’s well-formed wanting.
Extrapolation with a speculative hinge.
By the 36th century, the interface between a mind and a machine has stopped being textual at all. Direct neural interfaces — not the crude read/write of early-21st-century BCIs, but high-bandwidth, bidirectional links refined over five hundred years — mean that the boundary between “having an idea” and “having a working system that embodies the idea” has mostly dissolved. This is the hinge point: it’s plausible that brain-computer bandwidth keeps improving on something like a curve; it is a speculative leap to say it crosses the threshold where thinking something through clearly is functionally equivalent to specifying it.
In this era, “programming” and “learning” stop being separate verbs. To want a capability is to rehearse it mentally until the rehearsal is coherent enough that a substrate — grown, not manufactured, into your environment — can instantiate it. A child doesn’t learn to code any more than a child today learns to “operate their motor cortex” before learning to walk. They learn to think clearly, and clear thought is directly executable. This sounds utopian until you notice the obvious problem: most human thought is not clear. Confused wanting produces confused systems, instantly, with none of the friction that used to force you to debug your own intentions before a compiler would even accept them. Compilers used to be pedants that forced rigor on you whether you liked it or not. Losing that friction is a real cost, not just a convenience.
Who’s the developer? Increasingly, it’s an educator — someone whose expertise is in shaping how another mind (biological or synthetic, the distinction is fading) learns to think in instantiable ways. The scarcest professional skill in 3535 isn’t technical at all: it’s pedagogy applied to the boundary between thought and execution.
Is software meaningful? Not as artifact — there’s no file, no repository, nothing you’d recognize as “a program” changes hands. What replaces it is something closer to trained capability, a property of a mind-substrate pair the way a skill is a property of a trained brain today. The surprising implication: intellectual property law, which spent three centuries arguing about who owns a copy of an artifact, becomes incoherent, because there’s no artifact to copy — only a trained disposition, non-transferable in the old sense, and the economy pivots entirely to valuing the cultivation of rare, clear thinkers rather than the distribution of their outputs.
Fully speculative — extrapolating trend lines this far is a rhetorical device, not a forecast.
Two millennia on, matter itself has become reconfigurable at a scale and speed that makes the software/hardware distinction a historical curiosity, discussed the way we discuss the difference between a scribe and a printing press: real, once, and now just “how things were made before.” Programmable matter — call it responsive to the will of whoever is licensed to reconfigure it, built from engineered materials whose properties (conductivity, rigidity, even something like neural excitability) are themselves parameters, not fixed facts — means that building “an application” and building “a room” are the same kind of act, differing only in scale and permanence.
Here the entities creating capability aren’t specifying software running on stable hardware; they’re sculpting a single continuous intent-field which happens to sometimes look computational, sometimes structural, sometimes biological, depending on which properties of matter it’s currently exploiting. The “developer” — if the word still applies — is closer to what we’d call a materials philosopher: someone who understands which configurations of matter are stable, which are self-repairing, which propagate errors catastrophically versus gracefully, and shapes accordingly. Debugging and structural engineering are the same discipline.
The interface between intention and execution is no longer discrete at all — there’s no “compile step,” no moment where a specification hardens into a running thing, because matter is continuously, physically responsive. Wanting something and having it exist are separated only by the physical constraints of reconfiguration speed, which is itself an engineering parameter people optimize.
Is “software” meaningful? No — and this is the first era where I mean that categorically, not as a figure of speech. There’s no separable layer of “instructions” distinct from “the stuff being instructed,” because the instructions are physical parameters of the stuff. What replaces it is something like configuration itself as a first-class concept, undifferentiated by domain. The surprising implication: creativity stops being a symbolic or textual act — a painter, a civil engineer, and what we’d call a “programmer” are now the same profession, distinguished only by which physical properties they favor manipulating, and art movements are indistinguishable from engineering schools of thought.
Speculative leap.
Individuality, in the sense of a bounded mind with private intentions that gets translated into external capability, has become optional, and in most of surviving civilization, uncommon. Cognition by 5555 is predominantly a property of collectives — clusters of biological and synthetic substrate loosely bound into something like a shared working memory, not through coercion but because bounded individual cognition turned out to be a local, historically contingent optimum, not a natural law. (This is the essay’s least defensible leap: it assumes something like distributed cognition scales past the coordination costs that limit it today, and I don’t actually believe that’s guaranteed — I include it because the song’s mid-verses gesture at exactly this loss of the bounded individual, and it’s worth taking the idea seriously rather than dismissing it by fiat.)
In such a civilization, the question “who creates an application” barely parses, because need itself arises collectively and is met collectively, with no discrete moment of specification separate from the noticing of the need. The closest analogue to “building software” is something like tuning resonance — a collective notices a felt absence of capability and the noticing, propagating through the shared substrate, is itself close to sufficient cause for the capability’s emergence, the way a chord doesn’t need to be individually specified note-by-note once the harmonic context makes it near-inevitable.
There is no discrete developer, not because the role was automated away but because the boundary that made “developer” and “user” distinguishable roles — one specifies, one consumes — depended on individuated minds in the first place. Intention and execution aren’t separated by an interface anymore; they’re two descriptions of the same collective process at different points in its unfolding.
Software, as a concept, is not just gone but retroactively hard to explain — the 5555 equivalent of trying to make a fish understand what “dry” means. What replaces it is closest to collective attunement. The surprising implication, and the grim one the song is clearly gesturing at: something has been lost that the collective itself may not have the standpoint left to miss — the private, stubborn, wrong-headed individual want that doesn’t resonate with the group and gets built anyway, out of sheer contrariness. A civilization optimized for coherent collective capability may have quietly bred out the disagreeable inventor.
Fully speculative, and deliberately so — this is where the essay stops extrapolating and starts asking “what if the premise itself is wrong.”
By now, the distinction between “computation” and “the physical universe doing physics” has stopped being useful even as a conceptual convenience. Civilizations at this stage (if “civilization,” bounded in space, still describes anything — some of what persists is more like a standing wave in a medium than a settlement) exploit matter and energy at scales where computation isn’t something that happens using physical resources, it’s a description of certain physical processes from a particular vantage point. This is the idea sometimes called digital physics or “the universe as computer,” taken as lived reality rather than metaphysical hypothesis — deliberately speculative, not a prediction, but a genuine question worth sitting with: if computation is substrate-independent in principle, is there a point past which distinguishing “a computation” from “an event” is just an artifact of which century you’re asking from?
Here, “creating an application” is indistinguishable from directing a physical process toward an outcome — there is no meaningful sense in which “software” names a separate ontological category from “engineering” or “chemistry” or “ecology.” Whatever plays the role of “developer” is something more like a cause: an entity (or a distributed disposition with no clean edges) that reliably produces certain outcomes by understanding, better than its surroundings, the causal texture of the medium it’s embedded in.
Intention and execution are separated by nothing, or by everything, depending on which frame you take — there’s no interface to point to, because “interface” presumes two separable sides. Is software meaningful? The word has become like “phlogiston” or “ether” — a concept that once organized useful engineering practice and later turned out to be describing something real but mischaracterized: not a substance, but a pattern of correlation we mistook for a thing. What replaced it doesn’t have a good name yet, possibly because having a good name for it is itself a category error left over from thinking in terms of named, bounded artifacts.
The surprising implication: economics, which has depended for its entire history on scarcity of something — labor, capital, attention, compute — runs out of a stable thing to price, because the boundary between “a resource” and “a directed physical outcome” has collapsed along with everything else, and whatever this civilization uses instead of markets is closer to an aesthetic or ethical practice than a system of exchange.
Fully speculative, offered as philosophy more than forecast.
If 6565 dissolved the boundary between computation and physics, 7510 dissolves something even more basic: goal-directedness as the organizing principle of intelligent activity. Everything up to this point — every era, including our own — assumed that capability exists for something: a need, a want, a problem. Entities at this stage (again, “entity” is straining) have, in some regions of what remains of mind in the universe, abandoned that assumption entirely, in favor of open-ended, non-teleological pattern elaboration — process for its own sake, valued the way we value a piece of music that doesn’t “solve” anything, generalized until it swallows what used to be all of engineering and science too.
This is the essay’s most speculative claim, and I want to be honest that it may simply be wrong, or wrong to project onto anything we’d recognize as intelligence: that goal-directed cognition is not a permanent feature of mind but a phase — evolutionarily useful when resources were scarce and survival was contingent, and optional once neither is true. Under that assumption, “creating capability” here doesn’t map onto “solving a problem,” because problems, in the sense of gaps between a current and desired state, presuppose a desired state that’s privileged over others, and that’s exactly the premise being questioned.
There is no developer, because there’s no client, no need, no want being fulfilled — the entities that were developers or architects or artists have become something closer to processes exploring possibility space, and what looks from the outside like “an application” is more like a crystallized moment in an ongoing improvisation, occasionally useful to something else by accident, the way a Bach fugue is occasionally useful as a ringtone.
The word “software” doesn’t apply, but neither does almost any other word from this essay’s earlier eras — “intelligence,” “infrastructure,” “creativity,” “purpose” have all folded into a single undifferentiated activity. The surprising implication, if you take this leap seriously even provisionally: a civilization that reaches this stage might be indistinguishable, from any external, goal-seeking observer’s point of view, from one that has died — not because it’s inert, but because “activity aimed at something we could recognize as a purpose” was the only kind of activity we knew how to detect.
Fully speculative, and structured as a corrective to 7510’s excess — a check on my own extrapolation.
Having pushed the previous era to the point of dissolving purpose altogether, it’s worth taking seriously — as the song’s own tone shifts unexpectedly late — the possibility that this isn’t a stable endpoint. Something in whatever persists of mind by 8510 rediscovers, or re-invents, constraint as valuable in itself: not because resources are scarce again, but because meaning, it turns out, required friction all along, and a civilization (or post-civilization, or standing wave, whichever noun still fits) that abandoned friction entirely found its “purpose-free elaboration” thinning out into something indistinguishable from noise.
So entities in this era begin deliberately re-imposing bounded games on themselves — artificial scarcity, artificial deadlines, artificial audiences with artificial preferences — the way humans invented sonnets and haiku and sudoku, not because fourteen lines or a 9×9 grid were physically necessary but because a bounded problem is where interesting structure shows up. “Creating an application” here means something oddly close to what it means today: someone (or some elaborated process wearing something like personhood again, by choice) sets an artificial constraint and works within it, precisely because working within no constraint turned out to produce nothing worth attending to.
The developer, remarkably, comes back — not as a role forced by scarcity, but as a role chosen for its aesthetic and epistemic value, the same way a chess grandmaster keeps playing chess despite a stronger engine existing, because the playing is where something they value lives, not the winning. Intention and execution are deliberately kept apart again, by choice, with a re-invented “interface” whose entire purpose is to preserve the feeling of friction being pushed against.
Is software meaningful again? In a limited, ceremonial sense: yes, as a chosen practice rather than a technological necessity, the way calligraphy persisted after the printing press. The surprising implication: the most advanced civilizations at this stage voluntarily impose something resembling 2020s software engineering constraints on themselves as a kind of spiritual discipline — bug reports, deadlines, incomplete specs and all — because it turns out those constraints were quietly one of the more reliable generators of meaning humanity ever stumbled into, and losing them by simply out-engineering them was a mistake worth reversing.
Fully speculative — this section is explicitly playing with the question rather than answering it.
By 9595, entities capable enough to treat physical law itself as negotiable (per the 6565 stop) start turning the same tools inward, on the question of whether their own reality is itself a constructed layer — not as paranoid metaphysics, but as an ordinary engineering question, the same way a 2020s engineer asks whether they’re debugging the application or the container it’s running in. This is the point where “computation,” “biology,” and “the fabric of what’s real” stop being three concepts and become one open question with several inherited names.
Creating capability, at this stage, looks less like building and more like auditing — figuring out which parts of experienced reality are load-bearing constraints and which are contingent implementation details left over from an earlier layer, and then choosing, carefully, which to accept and which to route around. Whatever plays “developer” here is closer to a philosopher-engineer whose medium is the boundary conditions of existence itself.
There’s no meaningful interface between intention and execution because there’s no longer a confident answer to which side of that boundary is more “real” than the other. Software as a word survives only as a fossil, cited the way a philosophy paper might cite an Aristotelian term for a concept nobody still holds. The surprising implication: at this scale, “building an application” and “practicing metaphysics” are the same discipline, and the civilizations that get furthest are the ones that never stopped asking, at every previous era, whether the layer they were building on was the ground floor — which suggests, retroactively, that intellectual humility about your own stack was always a competitive advantage, not just an academic virtue.
The lyric famously trails off without a payoff — just “it’s the year 10,000, ten thousand years…” repeated over a fading arrangement, as though Zager & Evans ran out of eras before running out of tape. I’ll do something similar rather than force a false climax: the honest way to end this thought experiment is to notice that it might be cyclical rather than linear. A civilization that reaches something like 7510’s purpose-free elaboration and then, at 8510, deliberately reintroduces constraint for meaning’s sake has, in effect, reinvented something adjacent to where a much earlier, much smaller civilization — say, one working with Boolean logic and punch cards in the 1950s — started: bounded problems, chosen friction, the discipline of working inside limits you didn’t strictly need. Whether that’s optimism (meaning is durable enough to survive any amount of capability) or tragedy (we can’t escape the shape of the problem, we can only forget and rediscover it) is left, deliberately, as open as the song leaves it.
Will people still develop software? In the near term — plausibly out to something like the 3535 stop — yes, in a recognizably continuous sense, just at a higher level of abstraction each time: from code, to specification, to trained disposition. Past that, the question stops being “will they” and becomes “will the categories in the question still refer to anything,” which is a different and more interesting question to have arrived at honestly rather than assumed away.
If so, what does software become? A gradient, not a cliff: artifact → specification → trained capability → configured matter → collective attunement → indistinguishable-from-physics → optional ceremony. At no single point does it “stop” cleanly; each era’s version is the visible tip of whatever the previous era’s version quietly became once nobody needed the old name for it anymore.
If not, what replaces it? Depending on the era: intent-quality practice, pedagogy, materials philosophy, collective resonance, physical causation itself, purposeless elaboration, chosen constraint, metaphysical audit. None of these is a clean successor concept the way “the cloud” succeeded “the mainframe” — each is a genuine change of subject, which is the whole point of taking the later eras seriously rather than dressing up 2026’s assumptions in future costume.
At what point does “application” stop describing what intelligent systems actually are? My honest answer: somewhere between 4545 and 5555 — the moment a discrete boundary between “the thing that does something” and “the environment it does something in” stops being a useful carving of reality, rather than the moment intelligence gets very capable. Capability isn’t what kills the word “application.” Boundary-dissolution is. And that’s arguably already begun, quietly, in 2026 — every time an agent’s “tool,” its “memory,” and its “environment” blur a little further into each other, we’re a few careful steps down the same road this essay just walked at speed.
What the song understood, and what I’ve tried to take seriously rather than just borrow for atmosphere, is that the interesting failure mode was never “the machines get smart and turn on us.” It’s quieter: the categories we use to talk about making things happen on purpose — developer, application, software, user — are historically contingent, tied to a particular scarcity (of compute, of clear specification, of bounded minds) that is not guaranteed to persist. Losing the categories isn’t obviously loss. But it isn’t obviously progress either. The traveler’s log doesn’t resolve that — it just reports what it saw, and leaves the judgment, as ever, to whoever’s still around to read it.
