Greg Egan

To-read. Surfaced via Children of Time → Consciousness Upload and Bio-Synthetic Minds as the most rigorous fictional treatment of mind uploading and identity.

Australian hard-SF writer known for ideas-first fiction grounded in real math and physics — especially consciousness, identity, and the nature of reality.

Where to start

• Permutation City (1994) — uploaded minds, simulated realities, the continuity-of-identity problem. The direct rec from the upload note.
• Diaspora (1997) — posthuman/software minds; deep-future scope.
• Axiomatic (1995) — short-story collection; a good low-commitment entry point.

Why

• Ties directly to Consciousness Upload and Bio-Synthetic Minds.
• Adjacent to Neural Networks and Brain Scaling and Emergent and Collective Intelligence.
