Second Person, Present Tense -- by Daryl Gregory
At saturday house, the conversation turned to the computational theory of mind, and Rehana pointed me in the direction of this story about a girl who od's on a drug that dissolves your emergent consciousness.
Say you could buy this drug over the counter. Would people declare personality bankruptcy and take a recuperative vacation to build a new personality? I could see a market for personality bootcamps, where you reboot your brain in a safe environment.
Hopefully, enough would be learned from drug trials to allow people to modify their personality in situ, without having to resort to a full nuke and pave.
