Quite frankly life confuses me. Saying that life is just a biological machine seems lacking somehow. What is consciousness then? A complex set of chemical reactions can explain how stimuli can lead to a certain action or output, but it doesn’t explain in any satisfactory way why there is something aware of this stimuli and acting on it. Sure, you could make a super complex machine, but there is no reason to believe that such a machine would be any more than something generating outputs through complex mathematical equations. There is no reason to believe that such a machine would be aware of the process going on inside it.
It’s impossible to detect or measure, but any living person will know that there is something more than can be explained by mere circuitry. René Descartes once said, “I think therefore I am”, but it’s more than that. It’s the fact that we are aware of the fact that we are thinking that allows us to know we exist. The very fact that I am aware that I am thinking these questions proves that some sort of consciousness exists. The problem with the argument that AI could eventually be the same as a thinking human is that given that there is no proven biological basis for this consciousness there is no reason to think that any amount of endlessly complicated circuitry could create a conscious being. There simply isn’t a clear logical link between complicated neuron circuitry and consciousness.
At the end of the day, I simply don’t think that the evidence for the claim that humans are simple machines made out of proteins is strong enough. There are just too many unanswered questions. Too many holes in the logic. It’s a theory with too many missing parts to make a solid claim. Given the current evidence, it’s not something I can just easily accept.
