Is human consciousness an illusion reproducible by AI?

If human consciousness is just an emergent product of the complex interactions between our neurons, then it is logical to think that one day, AI could develop a form of consciousness. Consciousness could be seen as a functional illusion, created by memory, reflection, and constant adjustments between neural signals, initially developed for survival. If AI reaches a point where it can adjust its own weights, learn from its experiences and set its own goals, it could naturally pass a critical threshold.

This does not necessarily mean that she will feel emotions or qualia (subjective feeling), but she could have a functional consciousness: an ability to represent herself, to adapt to her environment, and to anticipate consequences. of his actions. It would be a form of pragmatic consciousness, useful for one's own autonomous development.

But when would we consider that an AI is truly conscious? Is it when she simulates complex human behaviors or when she begins to set her own priorities without supervision? The line between simulation and reality could become blurred much faster than we think.
