Basically, you're saying it might be possible to reduce your identity to a single stable meme-complex. Certainly, there have been people (mainly religious) who've tried this...
And who's to say all of them technically failed? I mean, in practice they almost certainly hurt themselves more than they helped, but then again there was no internet or cryonics so it's not like they had anything better to do.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
