The point is control over this process, ability to make decisions over development of oneself, instead of leaving it largely in the hands of the inscrutable low level computational dynamics of the brain and influence of external data. Digital immortality doesn’t guard against this, and in a million subjective years you might just slip away bit by bit for reasons you don’t endorse, not having had enough time to decide how to guide this process. But if there is a way to put uncontrollable drift on hold, then it’s your own goal slots, you can do with them what you will when you are ready.
