Wiley posted part of an article about the preservation of brains after death:
I have been reading about the Brain Preservation Foundation (BPF), which hopes that chemical and other methods, including a refined version of plastination, will enable brains to be preserved with such fidelity that memories, personality, and even identity can be preserved.
This may well seem reminiscent of the older cryogenic preservation projects which have not always had a good press over recent years, though they still continue to operate and indeed have refined their processes somewhat. But although the BPF also has a vision of bringing people back to life after their natural death, it is in many ways a different kettle of fish. It does not itself offer any kind of service but merely seeks to promote research, and it does not expect to see a practical system for many years
Traditionally, attempts to preserve brains have been portrayed as sinister plots to prolong the depredations of evil dictators both terrestrial:
Sure, if you put an evil brain in a jar, you have an evil brain in a jar. Not a lot of good guys seem to get the treatment, with a memorable exception, and even then, he was just used as a glorified building superintendent:
Why wouldn't having your brain preserved outside of your body actually be a good thing? If the aliens want to put your brain in a jar and take it around to have interplanetary adventures, why fight it? Sure, it would suck to have your brain stuck in some facility on a remote planet running the sewer system, but it wouldn't be bad to have your brain taken along on jaunts to thirty-seven different celestial bodies—planets, dark stars, and less definable objects—including eight outside our galaxy and two outside the curved cosmos of space and time. Even better, maybe the Brain Preservation Foundation can preserve Taylor Swift's brain, so she can keep breaking up with dudes for millennia and writing songs about said breakups. Even better, Taylor Swift's preserved brain can be placed in a space probe so she could break up with every dude in the universe.
