I dismiss it completely. "The human condition" as a phrase is usually associated with pain, suffering, horror, inhumanity to others, and so on. It's not a pleasant phrase.
The current state of 'being human' or current society have no inherent right to stay as they are. They change every day with every invention, and if longevity changes them again, so be it. If people opt-out of longevity, so be it. But the changes wont be magic - people will still be alive to guide and choose how society changes, it wont be instant-hell in a handbasket. And if it is, you can find a suicide booth and be in the same state you would have been otherwise.
