    Currently many futurists praise cryonics, according to them - a way to immortality.
    But if we frozen human brain and after that successfully defrosting it, will we obtain the same personality as before?
    From what I know about brain functions I have suspicion that human personality could me more of dynamic than static process.
    It could be rather compared to REM memory than HD. Processes which exist in human brain should continue uninterrupted in order to preserve personality. Once those processes do stop and energy converted to heat, entropy is irreversible. So, what we will obtain when defrosting human is just newborn personality similar to the old one. Could this hypothesis be proved or disproved?

    It's difficult to say. We don't even know what causes personality.

    First you would need to actually be able to revive a frozen brain.

    Since nobody has frozen an actual living person yet it seems unlikely that they can be recovered.

    Another factor is that the personality of a person could depend on experiences/environment also. I guess we don't fully know (meh..)

    Allot of applications such as space travel are thought to depend on cryonics. I wouldn't be surprised if cryonics experiments become popular in the near future. Say 20 years.
