In these discussions, "subjective" and "objective" are jargon. "Subjective" basically means existing only from the point of view of an observer. "Objective" means existing independently of any observations or experiences.

For example, playing a video game, there is some kind of objective physical activity occurring in reality. Subjectively, you perceive a cartoon world with Mario bouncing around on koopas. If the CPU has its own subjective experience of the very same objective physical phenomena, it probably doesn't involve the perception of Mario and koopas.

I think there is probably tremendous value in figuring out what it is about the universe that enables these different subjective experiences, when and how they arise, how they're similar and different, etc.
