Would immortality be a blessing or a curse for the one who has it?

The prospect of immortality, at first glance, might seem like a divine gift, an escape from the finality of death. Imagine endless time to learn, to explore, to witness the unfolding of history and the progress of humanity. There would be no more fear of the unknown, no more grief over lost loved ones in the traditional sense, just an eternal existence to savor. It could be a chance to achieve true mastery in any field, to experience the fullness of life without the ticking clock of mortality. However, this supposed blessing quickly reveals its darker side. Eternity is a vast and daunting expanse. The joys of life are often amplified by their fleeting nature. Without the contrast of an end, would achievements hold the same weight, would love feel as precious, or would moments of happiness be diluted by their endless repetition. The world would change, societies would evolve, and everyone the immortal knew would eventually turn to dust. The loneliness of outliving everyone and everything would become an unbearable burden, a constant reminder of their own unchanging state in a perpetually changing universe.
