If you believe Noam Chomsky’s philosophy that mind is innate, separating from language, then self sense AI is impossible. Chomsky’s theory explains well why infants can learn any language so fast without formal training. I used to believe Chomsky’s philosophy of language.
If you believe Ludwig Wittgenstein's philosophy that language is a social construct, a social tool and meaning of language is defined entirely by how words are used in shared social environments, then Self sense AI is almost impossible. Because AI doesn’t have a social life. Actually AI doesn’t have a living life.
The main argument against self sense AI today is The Chinese Room which argues that today’s Large language models (LLMs) and neural networks are just parrots. They simulate understanding through syntax but lack actual semantic comprehension.
