[sci.nanotech] Utility Fog for crash protection

djoslin@yeager.bbn.com (08/24/89)

Why worry about the car wreck (or bomb, or whatever) in the first
place?  Wouldn't it be easier to "back yourself up" frequently
(incremental backup?) and have yourself reconstructed if disaster
ever strikes? 

Perhaps what is needed instead is a Fog that senses disaster and
rather than protecting you, dismantles you painlessly. Part of 
the dismantling process would involve recording your current "state"
just prior to the car/bomb/whatever impact.  The Fog can then 
endure the disaster fairly easily (how many G's can a Fog withstand?)
and then either construct itself into a memory cartridge with
a radio beacon, or travel to the nearest reconstruction location to
put together a new copy of you.  Or could it just reconstruct you
at some nearby safe location?  

>It would also probably be a good defense against Grey Goo.

Wouldn't it also be a good starting point for making Grey Fog?
If good Fog can defeat Grey Goo, then what defeats Grey Fog?

I'm not sure many people would want a backup.  Even if they did, they might
want to carry it with them, to make absolutely sure no one would steal it.

Consider the consequences of losing a copy of yourself.  Some unscrupulous
person might make copies of you and abuse them.

IMHO the worst thing that could happen would be if somebody let loose a
slightly damaged/modified copy.  It might take over your bank account.
If you're dead, it could claim to be you and discredit everything you'd
ever done.  It might repudiate all the opinions expressed in your books, 
and it might rape and murder in your name.  And nothing would be more capable
of doing this than a slightly modified you.

Both cryonics and downloading suffer from this fearsome possibility.
