Isn't there a medical condition that makes people forget the waking period after they go to sleep, and so begin the next day with a mindset (progressively) falling behind the world? Suppose you offer someone with this condition a half-day-long experience which would be as worthy (considering their actual goals) as anything they would ever have a chance of doing, if they agree to forget it immediately?
How much is half a day worth, if you only have a day, yet are reasonably certain you'all be around tomorrow?
I don't think I understand the riddle of experience vs. memory. I would daresay that means the concept is half-baked.
Within the TED talk, Daniel Kahneman poses the probably familiar philosophical quandary: if you could take a beautiful vacation and afterwards your memory and photo album was completely erased, would you still do it? Whether you would still do it illustrates whether you live in service of the experiencing self instead of the remembering self.
Part of what prevents me from understanding the riddle is that I believe vacations are worth more than the memories and photos: vacations change you.
Maybe you could argue that this change is also a form of memory in service to the remembering self, but I'm not sure that's what he meant. In his thought experiment on vacations he asks if you would still take a vacation if, at the end of it, you forgot the whole thing and all of your photos were deleted.
