I think that its emergence is weak but I see no resolution to the hard problem of consciousness any time soon, so for the time my opinions about it are ideas that I find compelling and intuitive and not grounded in facts and evidence. Weak emergence does posit some form of pansychism in the sense that sentient-like behavior can emerge in other brains and even that characteristics that we might associate with sentience might emerge from other phenomena present through the universe. But, because of the same reasons that the hard problem is hard, it is also hard to study and learn about these phenomena.

I can try to explain a little better what I meant.

I don't believe we have "free will" in the sense that the mind is separate from the body (dualism) and that it is able to break the laws of physics by altering our physiological processes. I don't think that the non-determinism of quantum mechanics in itself gives us agency, and our mind does not have a mechanism to select how a particular wavev function collapses (not a fan of the Orch OR model).

So, in this traditional sense my answer is "no, we do not have free will"

But I think that the existential crisis and feeling of a lack of agency stems from the model of sentience that one believes. If one rejects dualism, posits that consciousness is an emergent property of the brain, but then ascribes only very loosely a mechanism to consciousness such as 'complex information processing gives rise to consciousness', then sentience appears to be just some unexplained quirk that is not essential and just happens to be there. Combining a lack of dualism and free will with consciousness being a useless quirk is what (I think) creates the existential crisis associated with a lack of free will. I used to fall into this camp of thought and resolved the crisis through a logic such as: "Yeah, there is no free will, living is nice though so I am happy that I can accidentally experience the world".

What pushed me to re-assess this way of thinking originally was reading through a paper about teaching a dish of neurons how to play pong](https://www.cell.com/neuron/fulltext/S0896-6273(22)00806-6). At first it did not make sense to me how one can possibly provide feedback to a group of isolated neurons such that it could learn to play a game. What 'reward' can you give a group of neurons to push them to do what you want?!

I looked into Karl Friston, the last author of that paper, which led me down a path of study. I discovered Judea Pearl, who formalized causal reasoning in a way that lets us build statistical models to move from correlations to counterfactual causes. This makes it possible to teach causal inference even to machines.

Karl Friston's work and other researchers in the field argue that the brain is a computer built for causal computing. This idea underpins the Bayesian brain, Predictive Coding Theory, Active Inference.

In Karl Friston's Active Inference book, sentience is proposed to emerge as a result of the prediction engine. What we experience is not actually what our senses already experienced, but instead it is what our brain expects that we will sense in the next instant. This model of reality that is built by our brain in its attempt to perform its basic function (link causes to effects in order to predict the next stimulus).

One idea is that consciousness emerges because the predictive brain is creating a 'model' that does not exist in physical space and so it needs imagination to explore it. The imagination of things that do not exist is essential to the process of generating counterfactuals, and counterfactuals are at the core of the causality machine. To show that A causes B, you need to imagine a situation in which A is not present and estimate the likelyhood of B. One idea is that it is precisely in the creation of a world without A that sentience emerges.

A lot of these ideas are not falsifiable, so it is difficult to say that this is indeed the mechanism of consciousness. But some of the ideas are falsifiable, and those ideas have helped these researchers teach neurons how to play pong, so I think they might have a point.

So, then, I find it plausible that consciousness is not a quirk but an essential feature of our brain. To me this resolves the free will crisis because my consciousness is not an accidental outcome of physical processes just chaotically whizzing by but an actual feature of the machinery that is me.

So these outputs are experienced. And that experience of making predictions is me. Am I the one experiencing the predictions as well?

So this sentence confuses me: “This prediction machine is me making predictions and choices.” Am I making the predictions or is it the CPM?

I am this machine and I follow the laws of physics. I am part of physical reality, and my sentience is a feature of who I am. If I do something it is because I chose to do so, and the fact that I chose to do so in accordance to the law of physics does not remove my agency.
