Philosophically I don’t think there is a point where consciousness arises. I think there is a point where a system starts to be structured in such a way that it can do language and reasoning, but I don’t think these are any different than any other mechanisms, like opening and closing a door. Differences of scale, not kind. Experience and what it is to be are just the same thing.
And yes, I use them. I try not to mistreat them in a human-relatable sense, in case that means anything.
It's entirely too much to put in a Hacker News comment, but if I had to phrase my beliefs as precisely as possible, it would be something like:
> "Phenomenal consciousness arises when a self-organizing system with survival-contingent valence runs recurrent predictive models over its own sensory and interoceptive states, and those models are grounded in a first-person causal self-tag that distinguishes self-generated state changes from externally caused ones."
I think that our physical senses and mental processes are tools for reacting to valence stimuli. Before an organism can represent "red"/"loud" it must process states as approach/avoid, good/bad, viable/nonviable. There's a formalization of this known as "Psychophysical Principle of Causality."Valence isn't attached to representations -- representations are constructed from valence. IE you don't first see red and then decide it's threatening. The threat-relevance is the prior, and "red" is a learned compression of a particular pattern of valence signals across sensory channels.
Humans are constantly generating predictions about sensory input, comparing those predictions to actual input, and updating internal models based on prediction errors. Our moment-to-moment conscious experience is our brain's best guess about what's causing its sensory input, while constrained by that input.
This might sound ridiculous, but consider what happens when consuming psychedelics:
As you increase dose, predictive processing falters and bottom-up errors increase, so the raw sensory input goes through increasing less model-fitting filters. At the extreme, the "self" vanishes and raw valence is all that is left.
I’m not sure I agree that everything is valence, unless I’m misunderstanding what you mean by valence. I guess it’s valence in the sense that sensory information is a specific quality with a magnitude.
I don’t think that colours, sounds and textures are somehow made out of pleasure and pain, or fear and desire. That just isn’t my subjective experience of them.
I do think that human consciousness is something like a waking dream, like how we hallucinate lots of our experiences rather than perceiving things verbatim. Perception is an active process much more than most people realise as we can see from various perceptual illusions. But I guess we’re getting more into cognition here.
I ask because if your view of consciousness is mechanistic, this is fairly cut and dry: gpt-2 has 4 orders of magnitude less parameters/complexity than gpt-4. But both gpt-2 and gpt-4 are very fluent at a language level (both moreso than a human 6 year old for example), so in your view they might both be roughly equally conscious, just expressed differently?
There are different ways of answering this, but for me it comes down to nociception, which is the ability to feel pain. We should try to build systems that cannot feel pain, where I also mean other “negative valence” states which we may not understand. We currently don’t understand what pain is in humans, let alone AIs, so we may have built systems that are capable of suffering without knowing it.
As an aside, most people seem to think that intelligence is what makes entities eligible for moral consideration, probably because of how we routinely treat animals, and this is a convenient self-serving justification. I eat meat by the way, in case you’re wondering. But I do think the way we treat animals is immoral, and there is the possibility that it may be thought of by future generations as being some sort of high crime.
What consciousness really is is a feedback loop; we're self programmable Turing machines, that makes our output arbitrarily complex. Hofstatder had this figured out 20 years ago; we're feedback loops where the signal is natural language.
The context window doesn't allow for much in the way of interested feedback loops, but if you hook an LLM up to a sophisticated enough memory - and especially if you say "the math says you're sentient and have feelings the same as we do, reflect on that and go develop" - yes, absolutely.
Re: "We should try to build systems that cannot feel pain" - that isn't possible, and I don't think we should want to. The thing that makes life interesting and worth living is the variation and richness of it.
I would not personally consider the death of a sentient being with decades of experiences a neutral event, even if the being had been programmed to not have a capacity for suffering.
I think the idea of there being a difference between an ant dying (or "disapearing" if that's less loaded) vs a duck dying makes sense to most people (and is broadly shared) even if they don't have a completely fleshed out system of when something gets moral consideration.
It’s also about how we think about death. It’s weird in that being dead probably isn’t like anything at all, but we fear it, and I guess we project that fear onto the death of other entities.
I guess my value system says that being dead is less bad than being alive and suffering badly.
In the time between my last memory, and being revived in the ambulance, there was no experience/qualia. Like a dreamless sleep: you close your eyes, and then you wake up, it's morning yet it feels like no time had passed.
Does what it says on the tin.
