Calling it an illusion is not interesting. We define consciousness and subjective experience to match the very experience we understand.
There is literally no way for it to be an illusion, the definition itself precludes it. No matter how consciousness and subjective experience are implemented in the hardware of our brains, it is still a concept that we use to describe the experience, and the experience is real no matter what.
