The answer to what gives life meaning likely lies in the experience itself rather than the structure behind it. Even if we grasp all knowledge, have had every experience, comprehend every structure that governs reality, and have access to all, it is the act of continuously experiencing and engaging with those structures—our subjective interaction with the world—that brings meaning.

One can express thyself, even in a universe where all is known, because expression is a personal act—it’s the reflection of one’s own inner state and unique perspective, even if those perspectives have been seen countless times. Expression transforms even existential despair of having nothing to accomplish into something meaningful because it externalizes that feeling in a form only you could create, and in that way, it becomes valuable. Even to an omnipotent and eternal being, no one can perfectly replicate the expression your individual experience of existence from scratch, no matter how vast their knowledge may be; they can only imitate the expression itself or they would have to become you to fully share in your perspective.
