We now have theoretical frameworks suggesting that large language models might implement something analogous to consciousness—specifically, a “workspace” where information gets integrated before it shapes outputs. The J-space hypothesis, the concept of effective di…
Why this is News
Fourth distinct Electric Mind longform — not a note, not a chat claim. Archive API id 208363343 > prior ceiling 208220596. Continues the workspace → SAE microscope arc into measurement/practical guide territory (J-space, effective dimension). Distinct from Twitter-follower goal process; this is a cold-reader public essay product.
