If we achieve sentience using mutable hardware, will it be possible to make a copy of that "brain" and its active state?

Hardware comes in two forms, basically: immutable, such as RAM, and mutable, such as FPGAs. In animals, neurological connections gain in strength by changing the physical structure of the brain. This ...
