What do you mean by "take you"? 😉
They all satisfy Putnam's Def. of computational functionalism, I'm thinking* 🤔
*except for, possibly, his 3.

I am very happy to report that Models of Consciousness 6 has collected a total of 4,696.00€ of CO2 compensation, amounting to 187,840 kg CO2 reduction.
A huge thank you to everyone who contributed! - And especially to the main organizers Robert Prentner and Keisuke Suzuki, and Jonathan Mason!

Ultimately, our goal is to build an interdisciplinary research hub for Mathematical Consciousness Science. Don't hesitate to reach out if you would like to visit us! This is Bamberg, btw. 🤗 Cf. bamxi.org/research-vis...

Our mission is to facilitate state‑of‑the‑art research in Mathematical Consciousness Science.
To this end, we run workshops and conferences, organized in the form of sprints. Our first three sprints are devoted to Mathematical Phenomenology, Measurement Theory, and AI Consciousness!

It is an enormous pleasure—and a dream, really—to share that the University of Bamberg has approved an initiative dedicated to mathematical approaches in #ConSci. The initiative is called Bamberg Mathematical Consciousness Science Initiative, or BAMΞ for short.

Amazing piece!! 👏👏👏
One note on Challenge 2: The shoggoth and flicker hypotheses cannot deliver what is marked in yellow below, because that would require consciousness to be dynamically relevant, which conflicts with PU design constraints:
doi.org/10.1093/nc/n...
Any thoughts on this? 🤗

Claude's new system prompt instructs it to "avoid implying it has consciousness, feelings, or sentience with any confidence":

Very good points! I don't think animal consciousness is the *only* road , but definitely a road.
