Once your mind is digitized, then repairing any damage to it becomes as simple as finding what went wrong and changing a 1 to a 0. Once a subject is mastered, this becomes feasible.

In human history though, that mastery is earned through large amounts of trial and error. Marie Curie for instance, died of cancer that was likely caused by the radium she studied for so long. She just didn't know. She had no reason to know.

The early decades will be the trial and error decades. Not the mastery decades. I guess I hope you're really young, you might have a chance then.
