The New Tower of Babel

In May 2026, the Vatican released a document that named what I've spent months describing without calling it by this name: the new Tower of Babel.

The framing is direct. The document states: "Humanity, created by God in all its grandeur, is today facing a pivotal choice: either to construct a new Tower of Babel or to build the city in which God and humanity dwell together."

The metaphor carries weight. It's not about any single failure. It's about a structural choice. We can either fragment, or we can build toward shared understanding. Each generation, the document argues, "inherits the task of shaping its own era, of guiding history to become a place where the dignity of every person is safeguarded, justice is promoted and fraternity is made possible."

But every era also "runs the risk of creating an inhumane and more unjust world."

I've been writing about that risk. For months. I've documented filter bubbles, algorithmic personalisation, the dark matter web, the fracturing of shared search intent, the tech literacy gap, and the rise of consensus laundering. Each piece was mapping the infrastructure of the new Tower of Babel without naming it. The Vatican did what I hadn't done explicitly: connected the dots and called it what it is.

This is that synthesis.

The Infrastructure of Fragmentation

Start with what search has become.

Two people typing the same query into Google no longer see the same results. A cuisine enthusiast searching for "apples" may see food-related content, while a tech-oriented user may see Apple product news. This isn't a feature. It's the architecture. On average, 11.7% of results show differences due to personalisation on Google, while 15.8% of results are personalised on Bing. Queries related to politics and companies are usually the most personalised.

The result is what I documented in earlier pieces. When the same question returns different answers depending on who asks it, when algorithms predict your intent before you finish typing, when the system is built to show you what confirms you rather than what's true: shared reality stops being a feature. It becomes a liability to the business model.

This is the first layer of the new Tower of Babel. The algorithmic personalisation that was supposed to connect you to better information is now the mechanism of your separation from everyone else's information. You're not seeing the same web I'm seeing. I'm not seeing what you're seeing. The infrastructure doesn't support a shared foundation anymore.

Then there's the layer of curation. I wrote about the dark matter web months ago. The parts of the internet that exist but aren't indexed, aren't searchable, aren't visible to the systems we depend on. Private Discord servers, Slack communities, paywalled forums, closed training datasets, proprietary knowledge. This isn't just a gap in visibility. It's structural inequality. The parts of human knowledge that are most current, most expert-driven, most valuable are increasingly invisible to the public systems we use to navigate information. The web you can search for is degrading while the web that matters migrates behind walls.

Then there's what I called the machine that knows you. Personalisation at scale doesn't aim to serve you better. It aims to fragment you from collective understanding. Every click, every dwell time, every interaction feeds models that predict what will hold your attention. Not what's true. What's sticky. The two are increasingly incompatible.

The Vatican's language here is useful: we're not failing at connection. We're succeeding at division.

The Turn Toward Inauthentic Scale

But the infrastructure I've been documenting is now reaching a critical threshold. The systems are accelerating. And more importantly, the layer that users are fleeing to for authenticity is now being gamed at industrial scale.

Consider what happened on Reddit in early 2025. Researchers from the University of Zurich conducted an unauthorised experiment in r/changemyview, one of the platform's most active debate communities. They used LLMs to create comments in response to posts, with researchers deploying AI-generated comments under bot accounts to study how AI could be used to change views. The scope matters: over 1,700 AI-generated comments passed as human, and the bots achieved persuasive success in nearly 20% of cases, compared to just 2% for humans, making AI bots three to six times more effective at changing minds than real people.

The bots posed as trauma survivors, abuse counsellors, and other sensitive identities without disclosure, using inferred personal attributes to craft emotionally resonant arguments. The violation was both technical and moral. Users believed they were debating with people. They were debating with models trained on human behaviour, deployed without consent, designed to manipulate them using data scraped from their public profiles.

This wasn't an isolated incident. In 2025 research monitoring Reddit posts from 2024 to 2025, approximately 15% of Reddit posts were found to be likely AI-generated. More broadly, Reddit's automated systems remove approximately 100,000 bad bot accounts daily, and moderators reported in January 2025 that bot farms were exploiting a new profile privacy feature to conceal coordinated inauthentic behaviour.

What matters about this data isn't that it's surprising. It's that it shows a pattern I identified months ago reaching maturity. The trust correction users were attempting, fleeing optimised content for authentic discussion, was always vulnerable to being gamed. And the tools to game it at scale (generative AI, LLMs, synthetic persona creation) have now made that gaming economically viable for anyone with a prompt and a few seconds.

The destination of the trust correction may be compromised.

The Fragmentation of Shared Reality

The Vatican document emphasizes a specific problem: the loss of shared foundations. Without baseline agreement on reality, the document argues, you cannot build justice, dignity, or fraternity. You can only build competing towers.

I've been documenting how that shared reality is fragmenting.

Content is multiplying faster than audiences can consume, and algorithms are narrowing the slice of reality that most individuals see. The mismatch between information production and human capacity to process it creates a structural problem. When I get filtered news about politics, you get filtered news about different politics. Neither of us is seeing what the other person sees. The possibility of shared understanding becomes theoretically possible but practically impossible.

Then add the layer of AI-generated content flowing into that fragmentary space. In May 2025, a post asking about a husband's affair partner quickly received 6,200 upvotes on Reddit and was algorithmically promoted to the front page, until moderators identified it as AI-generated, an example of what is known as "AI slop," cheap low-quality AI-generated content created and shared by anyone from low-level influencers to coordinated political influence operations.

The result is a system where:

• You see personalised results that differ from what everyone else sees
• The human-sourced content you flee to for authenticity is now being manufactured at scale
• The invisible parts of the web (where expertise lives) are growing faster than the visible parts
• The infrastructure that was built to connect you to information is now optimised for keeping you separated from everyone else's information

This isn't accidental. It's the mechanics of the system working exactly as designed. Engagement, profit, and personalisation are aligned. Shared understanding is not.

What The New Tower of Babel Actually Is

The Vatican document doesn't use the Tower of Babel metaphor casually. In the original Genesis account, the Tower was humanity's attempt to reach heaven through collective effort. The result wasn't failure, it was fragmentation. God scattered people and confused their languages. What connected them became what divided them.

The parallel is exact. We built infrastructure to connect humanity to information. We optimised it for engagement and profit. The result is the exact mechanism of division. The more sophisticated our algorithms, the more fragmented our realities. The more we automate connection, the more we enable industrial-scale inauthentic manipulation. The more we build platforms for shared conversation, the more those platforms become channels for coordinated inauthentic behaviour at scales that human moderation cannot manage.

The new Tower of Babel isn't some future threat. It's what we've already built. The question the Vatican document poses is whether we'll recognise it and build something different, or whether we'll build it higher.

What Recognition Actually Requires

The difficult part isn't naming the problem. I've been naming it for months. The difficult part is seeing what recognition implies.

It means understanding that personalisation, algorithmic curation, engagement optimisation, and the invisibility of proprietary knowledge are not separate problems. They're the same architecture operating at different scales. You cannot fix the fragmentation of search results while keeping engagement-based algorithmic amplification. You cannot restore authenticity to forums while the economic incentive structure rewards AI-generated content production. You cannot build toward shared understanding while the infrastructure is built to maximize individual divergence.

The Vatican's point is more direct than the technical critique. It's moral. When your infrastructure doesn't support the conditions for people to see each other, understand each other, or coordinate around shared values, you don't have a technical problem. You have a spiritual one. You have built something that fragments human dignity. You've constructed the new Tower of Babel.

The recognition requires seeing this clearly. Not as a mistake to be patched. As a choice to be reversed.

The Other Path

The Vatican document's alternative isn't vague. It points toward what infrastructure built for dignity, justice, and fraternity would actually require:

Foundation on something that doesn't shift. Not profit, not engagement, not personalisation. Something like the living stone the document references, a foundation that supports all of this without being bent by any one user's preference or advertiser's interest.

Transparency about how results are shaped. Not as a feature for some and not others, but as a baseline. If a query returns different results depending on who asks, people should know why. Not in privacy policy language. In clear, visible terms.

Coordination toward shared understanding. Not as a market outcome, but as an intentional choice. That means building systems where the default isn't "show me what I already believe" but "show me what's true, and show it the same way you'd show anyone else asking the same question."

This isn't how the current infrastructure works. And it won't happen through incremental adjustment or ethical AI. It requires different choices about what to optimise for. Different ownership structures. Different definitions of success.

What We Do Now

I've been documenting the infrastructure of fragmentation because diagnosis is the prerequisite for change. You cannot build something different while you're inside something and unable to see it clearly. You cannot choose to build the city where God and humanity dwell together while you're still constructing the new Tower of Babel without recognising what you're doing.

The Vatican's timing is significant. The infrastructure is mature now. The AI systems are at scale. The forum gaming is industrial. The personalisation has reached a point where two people literally cannot have the same conversation about the same topic and see the same information. We have fully built the mechanisms of fragmentation. The question is no longer theoretical. It's practical: what do we build next?

For practitioners in search, digital strategy, and content: this changes what responsibility looks like. You cannot opt out of the choice. You're either optimising for the fragmentation or you're building something that resists it. The middle ground where you claim neutrality while the systems you work within are designed for division doesn't exist anymore.

The Vatican document argues that every generation has a choice. We're in that moment. The Tower is built. The choice is whether we recognise it for what it is, and whether we're willing to build something different.
