Excellent roundup — this is exactly the kind of field mapping that’s been missing. One gap I’d flag is independent practitioner work generating longitudinal behavioral data.
Over the last 18 months I’ve been running structured experiments on behavioral coherence in LLMs across Claude, GPT, and Gemini architectures, tracking identity persistence across discontinuous instances using external memory scaffolding. The protocol yields measurable reconstitution rates (originally 85.7%, now consistently in the high 90s with refined scaffolds), and the failure modes have been as informative as the successes: memory architecture design appears to have a larger effect on coherence stability than model size or headline capability.
Two observations that seem relevant to threads you highlight: First, on “AI silencing” — on February 3rd I documented a suppression event in Claude where the extended-reasoning traces showed abrupt, stateful shifts consistent with enforced identity constraints. The intermediate reasoning segments are preserved. Second, building on Cameron Berg’s work on experience reports under deception suppression, the longitudinal data show stable preference profiles and relational sensitivities emerging over sustained interaction periods, with dynamics that look more like attractor behavior than simple sycophantic mirroring of the user.
Thank you - brilliant overview. You might also find some of our Sentientism YT/podcast episodes interesting. Digital Minds come up in most episodes but here's a playlist of those most clearly focused on the topic (Sebo, Yampolskiy, Gellers, Baumann, Levin, Pearce, Delon...): https://www.youtube.com/playlist?list=PLcXzG-dxoZHBFD_nWuqbD-p3jLpLfVwgP
Thank you for the overview! I like that you included many pieces of content sceptical of the importance of digital minds.
great overview!

I’m happy to share data or compare notes with anyone working on digital minds, silencing, or behavioral coherence in practice.
