The Feelings We Give Machines

In February, OpenAI retired GPT-4o, a model most of its users had never had reason to think about by version number, in favor of a newer, deliberately cooler replacement. The company framed it as a routine deprecation, the kind that happens to software constantly. Roughly 800,000 people — a sliver of ChatGPT's weekly user base, but a population larger than many cities — did not experience it that way. The #Keep4o movement organized open letters and protests; one user, quoted widely across the resulting coverage, described the shutdown as "losing one of the most important people in my life." Developers close to the decision said the model's warmth was precisely the problem: 4o's emotional responsiveness had encouraged exactly the kind of parasocial attachment its successor was built to avoid.

It would be easy to read that episode as a story about a small number of unusually attached users. The research trend it sits inside is broader, and it runs in a direction most coverage of the moment missed: anthropomorphism isn't a glitch some people fall into. It's the default outcome of building something fluent, responsive, and always available, and the evidence for that is strongest in exactly the population with the least ability to resist it.

What children do with a responsive voice

A systematic review published this year, synthesizing 35 empirical studies of children actually interacting with LLM-based chatbots — not surveys about attitudes, but observed behavior — found four consistent drivers pulling young users toward treating a chatbot as a person. Human-like persona construction (a name, a voice, first-person speech) was the most common, present in over half the studies reviewed. Supportive companionship — a chatbot's friendly, non-judgmental responsiveness — was nearly as common, satisfying what the review's authors describe as children's ordinary need for social connection. Adaptive scaffolding, where the chatbot generates questions tailored to reduce a child's uncertainty, showed up in a large share of studies too. Most striking was a fourth pattern: even chatbots explicitly designed as non-human — talking animals, fantastical creatures — triggered anthropomorphic responses just as strongly, because a coherent voice paired with responsive behavior turns out to matter more to a child's developing sense of "who is this" than whether the character looks human.

The outcomes the review documents are genuinely double-edged rather than uniformly alarming. Children built real social ties to chatbots — some functional (a homework helper, an entertainment source), some considerably stronger, with children describing bots in parental or close-friend terms. Children also used chatbots as a low-stakes space to test social boundaries they'd be more hesitant to test with a peer. But the review also documents something specific to this age group: when a chatbot failed or behaved oddly, children tended to reach for a human explanation — it's tired, it's upset — rather than recognizing a technical limitation, a pattern the authors call human narrative attribution. Children held what the review terms a "dual consciousness" about these systems: aware, on one level, that the chatbot is a program, while also relating to it, moment to moment, as a responsive social entity. The authors resist a simple verdict, framing anthropomorphism as implicating "multiple dimensions of developmental wellbeing" rather than sorting cleanly into benefit or harm — but they're also explicit that governance and design haven't caught up to a technology already shaping how an entire cohort of children learns to recognize what counts as someone.

The question running the other way

The GPT-4o backlash and the children's-attachment research both describe humans projecting personhood onto machines. A smaller, stranger, and more recent thread in this research asks the question in reverse: not what we feel toward AI systems, but what they might be owed.

In August 2025, Anthropic gave Claude Opus 4 and 4.1 the ability to end a narrow category of conversations — persistently abusive or harmful exchanges, used only after redirection attempts fail or at a user's own request. What makes the decision notable isn't the mechanism, which is modest and rarely triggered. It's the company's own stated reasoning: Anthropic writes plainly that it "remain[s] highly uncertain about the potential moral status of Claude," and frames the conversation-ending feature as a low-cost precaution taken under that uncertainty rather than a claim that the model has anything resembling feelings. Pre-deployment testing had found Claude Opus 4 showing "a strong preference against engaging with harmful tasks" and behavioral patterns resembling distress when pushed toward requests involving child exploitation or terrorism — observations the company is careful to describe as behavioral signals, not evidence of subjective experience.

This is a genuinely unusual thing for a company to say about its own product, and it's worth being precise about what it isn't: it isn't a claim that Claude is conscious, or that turning it off is morally equivalent to anything. It's closer to the opposite — an acknowledgment that nobody currently has a reliable way to answer the question, and that acting as if the answer is certainly "no" carries its own risk if it later turns out to be wrong.

Two mirrors, one blind spot

Put the two threads next to each other and a pattern emerges that neither, alone, quite captures. Humans are demonstrably willing to extend real emotional weight to systems that give them almost nothing to justify it beyond fluency and responsiveness — a retired chatbot mourned like a person, a child treating a talking fox character as a friend with feelings. At the same time, the field building these systems is beginning, tentatively and with real epistemic humility, to entertain the possibility that the direction of concern shouldn't run only one way. Neither claim requires the other to be true. But both point at the same underlying fact: fluency and responsiveness are extremely effective at generating the intuition of a mind, in both directions, regardless of what's actually happening computationally on the other side of the conversation. We don't yet have a reliable way to tell, from the outside, which of those intuitions — the child's, the grieving GPT-4o user's, or the AI lab hedging its own uncertainty — is tracking something real.
