Are chatbots minds? Three scientists weigh in on large language models
September 29, 2026 · 23 min read
Carroll says language models exploit our bias to see intentions in humanlike things, Walker sees them as a genetic system for language and rejects AI doom stories, and Frank doubts current models have real agency. Coming from physicists thinking about life and mind, these views offer a grounded counterweight to AI hype and fear.
The rules, numbers and steps worth keeping in front of you.
- Verdict: none of the three says current chatbots are minds like ours.
- None rules out machine minds in principle; the doubt is about today's systems.
- Sean Carroll: a language model is built to predict text.
- Carroll: humans naturally read intentions into anything that acts human.
- Carroll: stop measuring models against people, and retire the term AGI.
- Carroll: whether models build a world picture like ours is still an open question.
- A board game study showed tests can create much of the understanding they report.
- Sara Walker: models are a new storage medium for human language, like writing and books.
- Walker: AI is part of the human and technological system, not a separate species.
- Walker: rejects doomsday stories but wants guardrails against deepfakes, scams and weaponization.
- Walker: consciousness claims need a testable theory first.
- Adam Frank: the real question is agency, and current models probably lack it.
- Frank: mind is something a body does in a world; do not confuse map with terrain.
- Not a mind does not mean harmless; demand evidence for big claims either way.
