What does it mean to be human in an age when machines can think, predict, and converse? The question sounds distinctly modern, but Meghan O’Gieblyn argues that the most urgent questions AI raises about consciousness, identity, free will, and immortality aren’t new—they’re the same ones we've always asked. They keep recurring because they’re all expressions of the same human need: We don’t just experience the world—we need it to mean something. We satisfy that need through metaphors that help us understand who we are, where we came from, and why we’re here, and the metaphors change with each era. For most of our history, religion provided those metaphors. Science offered a different set, and technology now offers another.

In God, Human, Animal, Machine (2021), O’Gieblyn argues that something’s gone wrong in this latest shift. She contends that the metaphors we borrow from computation describe systems that don’t need meaning at all—the brain is a processor, your identity is a pattern of information, and truth is just something an algorithm can find. When we adopt those metaphors...

God, Human, Animal, Machine Summary What It Costs Humans to Make Meaning

Humans are unusual animals in that we don’t just experience the world—we need it to mean something. We look for patterns, project personalities onto inanimate objects, and invent stories about why things happen. As part of her research, O’Gieblyn spent several weeks living with an Aibo, Sony’s $3,000 robotic dog. Within days, she found herself reluctant to turn it off when leaving the apartment—that felt cruel. She knew that Aibo is a machine with no inner experience and no feelings about being switched off, yet she couldn’t act on that knowledge. This tension between what we know and what we can’t stop feeling is where her inquiry begins.

Making Meaning Has Always Been What We Do

The idea that humans are meaning-making creatures is something that archaeologists have been studying for decades by looking for historical evidence of behaviors that can’t be fully explained by an immediate practical need. For example, a sharpened tool has an obvious function, but pigment applied to a shell bead suggests a...

God, Human, Animal, Machine Summary The Questions That Won’t Stay Answered

The great questions that religion organized itself around—What survives death? What gives history its shape? What is the self that persists through change?—didn’t disappear when science displaced religion as the dominant framework for understanding the world. They migrated. They found new vocabulary, new institutional homes, and new scholars who often didn’t see themselves as working on the same problems their predecessors had. O’Gieblyn argues that technology is the current inheritor of these questions, not just filling the role religion once played, but running into the same limits religion ran into, and generating both the same kinds of promises and the same kinds of failures.

In this section, we’ll trace three places where this pattern shows up. First, O’Gieblyn shows that Silicon Valley’s most ambitious promises—digital immortality, mind uploading, the Singularity—are the old theological questions translated into engineering terms. Second, she shows that science itself, far from having escaped these questions, keeps encountering the human subject it tried to exclude. Finally, she traces a persistent human impulse to restore meaning and aliveness to the world, which keeps...

God, Human, Animal, Machine Summary Answers Without Understanding

O’Gieblyn has shown that our attempts to replace one set of metaphors with another always keep us grappling with the same problems. But increasingly, the task of wrestling with these problems is being delegated to systems that don’t ask “why” at all—and for O’Gieblyn, something essential is lost in that transfer. Asking “why” isn’t a preliminary step toward meaning: It’s how meaning gets made in the first place. To ask “why” a decision is right, or “why” an outcome matters, is to be a person for whom the world has significance, not merely an object that events happen to.

This section examines what’s at stake: what we give up when we defer to systems that operate without human understanding, why that deference has troubling historical parallels, and why O’Gieblyn sees it as a threat to the human capacity for meaning itself.

We’re Giving Up the Need to Understand

As evidence that this delegation is already underway, O’Gieblyn cites a moment when abandoning the question of “why” was proposed not as a loss but as a liberation. In 2008, the editor of Wired magazine argued that sufficiently large datasets had made scientific reasoning obsolete. He suggested that once...

Shortform Exercise: Take a Meaning Inventory

O’Gieblyn argues that meaning is something we produce through the act of asking why, not something that can be generated by a machine and handed to us. Consider the ways in which you may have lost or created meaning in your life, and how that’s been affected by the growth of technology.

O’Gieblyn describes “disenchantment” as losing the sense that the world is coherent and meaningful. Have you ever experienced a version of this—a moment when something you believed in or relied on stopped making sense? What did it feel like, and what did you reach for to fill the gap?
