Clearly consciousness is an emergent property of certain kinds of network, independent of the substrate within which the network exists.
We could make a very dumb biological calculator out of a few genetically-engineered neurons that would very obviously not be conscious.
It's still an open question if we can embed consciousness in our current microchips if we had enough of them together (which I think we currently don't), or if it requires some other physical process we don't fully understand, e.g. quantum. I strongly doubt it does require any quantum shenanigans, but even if it did, we can and will find all sorts of ways to make computers that can perform those shenanigans too. Eventually we're just going to stop being able to move the goalposts, unless you set those goalposts in magic-land.
And say what you want about meat but we don’t seem to find consciousness in rocks or plants or clouds or hairdryers. And the buddists report that some very strange things happen if you meditate for years on end but obviously they must be talking shit and making it up because it’s not testably scientific.
My view is physical, functional, mathematical and informational explanations are abstractions from shared experiences. Abstractions remove the experiential aspect to arrive at something objective so we can understand the world around us, since experiences are creature and to some extent, individually dependent. This is Nagel's ultimate point in What It's Like to Be A Bat paper about the objective/subjective divide. And probably related to Kant's argument about phenomena vs the noumena outside experience. We try to understand reality via abstraction.
And it has nothing to do with magic. It's an epistemological situation we find ourselves in, which may or may not tell us something fundamental about the world. Depends on your metaphysical assumptions as to what can fundamentally exist.
I happen to agree that this is likely, but it absolutely is not "clear" that this is the case.
1. a unique property of a specific type of biological tissue, not substrate independent
2. pan-consciousness: everything is conscious, but degrees of it vary, it's as much a part of the universe as gravity
3. a soul - some of sort of non-physical entity that confers consciousness but is specific to an individual
4. external consciousness: brains as receivers for consciousness, not the generator
5. specific only to humans and not substrate independent (i.e. rooted in physiological structures but not replicable in non-human form)
There may be more.
Leech neurons used to implement a calculator.
Are you suggesting that applications above some level of complexity can't be implemented using biological components? Because I'm pretty sure all I need to show you is a NAND gate in order to prove that arbitrary computation is possible.
I still wouldn’t argue that this brain in a Petri dish is, in any way, conscious. Despite it sharing the exact same substrate as everyone around me.
