I was reading an article today about a coastal city in Southern California — how people have been moving there because the community aligns with what they’re looking for. The article framed it as a story of attraction and economics. People leaving one place because they felt they didn’t belong, going to a place where they found their people and how this increased the value of homes in that community. The pull of alignment. The growth of an ecosystem.
It was a fine article. Typical of how these things get reported. But the thing that stuck with me wasn’t what it said. It was what it didn’t say. The unexplored other side.
Because, for every person who moved to that city because it felt right, there’s someone who moved away because it stopped feeling right. That person isn’t part of the article. They aren’t part of the headline. And they aren’t part of the author’s research. They just quietly packed up and found somewhere else — because that’s one way migration works. Systems like cities aren’t infinite in resources or culture — and when either runs out or changes, the population shifts with it. The population reflects a steady state for what the city can support, not an absolute — and a single article capturing a single point in time doesn’t describe the whole system.
In ecology, this has a name: niche displacement. When a new species arrives in an ecosystem and thrives, it’s rarely because the habitat was empty. Something else got outcompeted and pushed to the margins, forced to adapt and evolve or be driven out entirely. Ecologists know to study both sides: the arrival and the displacement. You can’t understand what an ecosystem is becoming if you only track what showed up, not what it lost, and the effect of the loss on the system.
But we don’t seem to do that with human systems — at least not in the typical news article presented as researched fact. Most reporting on cities, on migrations, on platform shifts tells you who arrived and why — and stops there. We celebrate the growth and the investment value it creates. We ignore the displacement and the values that were lost. And then we treat half the picture as though it were the whole immutable thing.
The Ecology of Platforms
It’s the kind of pattern that, once you see it in one place, you see it everywhere. And it changes how you see everything.
Amphibians are what biologists call indicator species — organisms whose presence, absence, or health signals the broader condition of an ecosystem. Their permeable skin makes them hypersensitive to shifts in water quality, temperature, pollution — changes that haven’t shown up anywhere else yet. When frogs disappear from a watershed, it tells you something about the system before any chemical test does. The displacement is the data. Indicator species don’t cause the change — they reveal it. They’re the early warning system for shifts that are already reshaping the ecosystem beneath the surface.
Amphibian populations worldwide have been collapsing since the 1980s. Over 40% of species are now threatened with extinction — the most endangered class of vertebrates on the planet. The frogs kept disappearing. Most of the world kept drinking the water.
That’s the pattern I keep seeing in human systems — not just the displacement itself, but the part where nobody reads the signals. The frogs are disappearing, and we write articles about the ponds.
When Elon Musk reshaped Twitter into X, the story I heard was about his vision for a new digital town square. But X lost roughly 33 million users after the rebrand. Journalists, academics, and entire professional networks migrated to LinkedIn, Bluesky, Mastodon, Threads, or just… nowhere, like I did.
What’s ecologically interesting is what happened next. X didn’t become an empty room — it filled with a different crowd, a different energy, a different set of cultural norms for acceptable human behavior. The platform didn’t shrink so much as it underwent succession. One community was displaced, and a different one colonized the same habitat. The departure shaped the destination just as much as the arrival did.
The displacement wasn’t a clean migration. It was a shattering — energy dispersed across half a dozen platforms and countless smaller communities. In ecology, when a keystone species is removed, the effects don’t just subtract. They cascade unpredictably. The ecosystem doesn’t lose one thing. It reorganizes around the void. And the thing that left reorganizes around survival — or it dies. Most systems are like living things. They don’t want to die, and they do everything they can to find a way to survive.
Tesla tells a similar story. A Yale study found that Musk’s political visibility has cost Tesla over a million vehicle sales since 2022. But competitors like GM, BYD, and Ford saw EV sales hold steady or climb. Customers didn’t stop wanting electric vehicles — they still want them, though the gap between what’s better and what’s practical is a conversation for another day. They stopped wanting that electric vehicle. The demand wasn’t destroyed. It was displaced — pushed into a different niche. The way a species doesn’t immediately vanish from an ecosystem but gets forced to compete for new territory or migrate entirely.
When the Invasive Species Look Like Innovation
Airbnb is a case study in displacement that took years to become visible. The original story was a classic disruption narrative: a platform that democratized travel, empowered homeowners, undercut overpriced hotels. That was the arrival. It was celebrated loudly and often — and it’s still the story they tell today.
The displacement crept in quietly. In Barcelona, neighborhoods with high Airbnb concentration saw rents rise 7% and property prices jump 17%. In New York, nearly 12,000 housing units were absorbed from long-term residents into the short-term rental market. House owners discovered they could make more money renting to tourists by the night than to families by the year — so they did.
It’s textbook invasive species behavior. The new arrival doesn’t just occupy available space — it outcompetes the native population for the same resources. And like most invasive species, the damage compounds quietly for years before anyone measures it. The arrival was celebrated in real time. The displacement was counted one family at a time, over a decade, long after regulators failed to adapt policy to the product being sold.
But here’s where the metaphor deepens — because Airbnb didn’t just displace the hotel industry. It’s converging toward it. Higher prices than hotels. Cleaning fees. Mandatory chores. Hosts who negatively review guests for not treating a rental with the devotion of an owner. Biologists call this convergent evolution — when unrelated organisms independently develop similar traits because they face similar environmental pressures. Airbnb, shaped by the same market forces that shaped hospitality, has started to resemble the very thing it wants to replace — but in many ways offers a worse experience for the same price. You’re paying hotel rates for cleaning fees and to do your own laundry and take out the trash. The disruptor hasn’t quite become the incumbent, but they sure look a lot like it.
Succession in the AI Ecosystem
The AI industry right now is a textbook case of punctuated equilibrium — long decades of invisible but steady, incremental progress interrupted by a burst of rapid change so compressed that you can watch the speciation, the competition, and the displacement happen in real time.
At OpenAI, the headline story was explosive growth — ChatGPT, billion-dollar valuations, a partnership that reshaped the industry. The displacement was quieter: a steady departure of the people who built it. Co-founder Ilya Sutskever left to found Safe Superintelligence — a company whose name is itself an implicit critique. CTO Mira Murati left. Jan Leike, who led the superalignment team, resigned saying he’d “reached a breaking point.” John Schulman, a co-founder, left to join Anthropic. The superalignment team was disbanded. The mission alignment team was disbanded.
Taken together, the departures trace an ecological pattern: the people most focused on safety were being displaced by the pressure to commercialize. The species that thrived in OpenAI’s early ecosystem — the cautious, the long-term-minded — were outcompeted by a different set of selection pressures.
And then, this month, a displacement so clean it almost reads as niche theory. The DOD designated Anthropic — founded by many of those same OpenAI departures — as a “supply chain risk.” Not for a technical vulnerability — because Anthropic didn’t want its technology used on American Citizens because they are powerful, autonomous weapons (surveillance is one kind of weapon) without human oversight. The Pentagon and the administration behind it turned a policy preference into a supply chain disqualifier — despite a party platform that otherwise champions deregulation and keeping government hands off private enterprise. A telling selection pressure. Hours later, OpenAI announced its own DOD deal. One company’s principled stance became another’s business opportunity. Competitive exclusion in real time.
The chain reaction kept going. ChatGPT uninstalls surged 295% in a single day. Claude’s downloads jumped 51%, surpassing ChatGPT for the first time. I was one of those data points.
That same weekend, I was deep in a personal project with Claude Code — it’s the best coding tool I’ve found for the way I work right now — and I hit my usage limit mid-flow. I’d been meaning to upgrade anyway, and I wanted to reward Anthropic for their stance, so I upgraded from Pro to Max. A small transaction in a chain reaction caused by one company’s principled stand.
Displacement at Every Scale
This pattern isn’t limited to tech or housing.
When the NCAA opened NIL deals in 2021, it was framed as a long-overdue victory for athletes. And it was. But the displacement has been destabilizing — over 4,500 football players entered the transfer portal in the 2025-26 window. Smaller programs became unofficial developmental leagues. Build a player up, watch him leave for a bigger check. The ecosystem reorganized around new incentives, and the organisms that can’t compete at that cost or scale will get displaced.
When a starting quarterback enters the transfer portal chasing a bigger program or a better NIL deal, there’s always a story about the move — the ambition, the opportunity, the upside. What doesn’t get written about is the offensive line that spent two years learning his cadence. The receivers who built timing routes around his release. The younger players who chose that program because of him. The arrival gets the press conference. The displacement just absorbs the hit and rebuilds.
But here’s what displacement ecology also teaches: the gap isn’t just loss. It’s habitat. When a dominant tree falls in a forest, the opening lets light reach the understory — and what grows into that space can be surprising. Oklahoma’s quarterback succession told that story three years running. Baker Mayfield left for the NFL, and Kyler Murray — a transfer from Texas A&M who’d been waiting in the understory — stepped into the light and won the Heisman. Murray left, and Jalen Hurts — displaced from Alabama’s starting role by Tua Tagovailoa — transferred in and became a Heisman finalist. Each departure creates habitat for the next arrival. You can’t predict what fills the gap from the depth chart. You can only see it after the succession plays out.
Weather Is Not Climate
Here’s where I think the real problem lives — not in the displacements themselves, but in how we measure and report them.
Every example I’ve described involves the same structural error: treating a snapshot as the whole picture. An article about people moving to a city captures a moment. A quarterly earnings report captures 90 days. A headline about a platform’s user growth captures a number. None of them capture the trend — and none of them capture the climate.
It’s the difference between weather and climate. If it snows heavily in April, someone will inevitably say “so much for global warming.” They’re not lying about the snow. They’re confusing a single data point with a pattern — and they don’t know enough about the system to realize they’re doing it. Weather is what happened today. Climate is what’s been happening for decades and what the trajectory suggests about the decades ahead. You cannot understand one by looking at the other.
Tesla’s Q1 sales drop is weather. The three-year brand erosion trend is climate. A single article about migration to a city is weather. The decades-long pattern of communities sorting themselves into ideological silos — what Bill Bishop called The Big Sort — is climate. In the 1976 presidential election, about 27% of Americans lived in “landslide counties.” By 2020, that number climbed past 58%. That’s not a snapshot. That’s a trajectory. But trajectories don’t get clicks or make good headlines.
And this is where the media itself becomes part of the ecology. Attention is selection pressure. It rewards stories about arrival and growth because those stories generate engagement. Stories about what that growth displaced are slower, harder to quantify, less shareable. Writers who optimize for that attention — and I think that’s a fundamentally different activity than journalism — end up selecting for a version of reality that only shows the canopy. The understory doesn’t trend. But it’s where the actual ecosystem lives.
Reading the Understory
I’m not saying ecological displacement is a perfect lens for human behavior. People aren’t species. Social systems are messier than food webs. The displacements aren’t always competitive or zero-sum, and they’re rarely as clean as a textbook model.
But as a thinking tool — as a prompt to ask “what was displaced?” — I’ve found it useful. Not because I want to be contrarian for its own sake, but because the question forces me to separate what I want to believe from what I actually have evidence for. When I read about a platform’s growth, I ask who never joined or left. When I hear about a company’s bold new direction, I ask what it cost in money and what they now cannot build or do. When I see a community rallying around a shared identity, I ask who no longer feels welcome enough to stay.
Ecosystems have no concept of right or wrong — those are human constructs laid over what the rest of life experiences as survival. An invasive species isn’t evil. A displaced population isn’t virtuous. The system reorganizes around whatever pressures are present. But because we’re the species doing the displacing and being displaced, we have the uncomfortable privilege of being able to see both sides — if we choose to look.
I tend to see the world through the lens of biology. It was the first discipline I went deep into — long before I wrote production code or thought about systems architecture. I learned about amphibian decline in the nineties, back when it was just starting to alarm the people paying attention, and the lesson that stuck was deceptively simple: pay attention to what disappears. The absence tells you more about a system than its most visible inhabitants ever will.
Things are almost never what they seem, and they are always more complicated than we want them to be. That doesn’t mean we have to complicate how we understand them. For me, it means losing the ego and keeping a beginner’s mind — staying open to the idea that I might be wrong, that I don’t know everything. The more questions I ask, and the more honestly I sit with the answers, the closer I get to something resembling the truth.
I keep thinking about that article — the one about the coastal city, the one that told a perfectly true story about people arriving and property values increasing. I wonder about the piece that didn’t get written. Or the one that did, but never found the same audience. The one about who left, and where they went, and what the place felt like after. That story is just as true. It’s just harder to tell, because displacement doesn’t announce itself. It doesn’t trend. It just quietly reshapes the landscape while everyone’s busy writing about the new growth.
