Well, no. You'd just be dead.

This thing that would not die though, this ability to know pain and pleasure, this continuing experience, it would remain in the event that my memories were all gone, presumably. THAT is the part I'm worried about. That the part of me that feels could wake up and have to go through the experience of realizing that who I am has been lost to brain damage.

Right now the DSM allows a depression diagnosis two months after a traumatic event

Is this supposed to rebut my objection? I don't see where you're going with this at all.

Do you accept "I should kill myself now, so I don't run that risk"? If not, how is that different.

Right now, there isn't a guarantee that I'm going to go through a medical procedure anytime soon. Going through a medical procedure, especially one that is new, or one that few people have been through, is likely to cause some sort of horrible side effects. We have no reason to assume that this technology will be flawless by the time we get to use it, no reason to believe it won't turn us into horrors.

It's different because not killing myself right now leaves me with a reasonable chance to have some number of happy years ahead whereas going through a medical procedure with unexpected side effects and risks may have a much greater chance of making me completely miserable for a long time.

I think our disagreement may have a lot to do with how much faith we place in the medical establishment.

If you haven't got experience with it, you can't know how bad it can be. Have you ever looked into how incompetent and horrible medical professionals and treatments can be?

I have a pile of statistics if you want a shock.
