# Contested concept: computer (as applied to the brain)

_**What you are reading**: one contested-concept page in Deliberus's deliberation graph. Deliberus maps human reasoning — including claims that are contested, mistaken, or extreme — so that disagreement can be examined precisely. A claim's presence here is not an endorsement: the graph records that someone argued it, how it connects to other reasoning, and how far scrutiny has gotten. The metadata on this page describes the state of that scrutiny, not the truth of the claim._

---

- **Contestedness**: semantic
- **Diagnosis**: Masks whether functional/computational equivalence between brains and AI systems is sufficient grounds for attributing brain-like properties (consciousness) to AI, or whether biological/physical realization is essential and the computer-brain analogy has been mistaken for literal identity ('map for the territory,' claim 87) by AI-consciousness optimists.
- **Canonical**: `/concept/computer (as applied to the brain)` (data: `/concept/computer (as applied to the brain).json`)

## Senses in use
- **'Computer' applied to the brain is merely a useful metaphor, not a literal description; actual brains do not permit a clean software/hardware separation, so computational/informational resemblance between a silicon system and a brain does not entail that the silicon system shares the brain's consciousness-relevant properties — much as simulating a hurricane computationally does not produce a real, physical hurricane.** — used in 9 claim(s)
- **The brain literally is a kind of computer (software/hardware separable the same way as artificial computers), making substrate-independent consciousness — e.g., arising in silicon systems like Claude — a live, literal possibility.** — used in 4 claim(s)
