[ExI] Philosopher claims - Consciousness can't be uploaded

[Keith Henson]

>From the clinic seed.

By the next day, Suskulan had animated
her image on the healing table so Zaba was able to speak through it
and to feel her mother holding her utility fog image when she visited.
Zaba’s real body was near freezing and 30 meters under the tata.

Her biological memory was being mechanically updated in her very cold
brain, and her consciousness was running in a swarm of fast
nanocomputers. Suskulan could have let her experience run even faster,
but he didn't want Zaba to get too far out of synch with her family
and the rest of the tata.

Mechanically constructed memory is a very efficient way to learn. With
Suskulan's help, Zaba learned to read her own language in a few hours,
to be fluent in English in 15 days (subjective), to an eighth-grade equivalent
education in 30 days, and to a rough understanding of the physical and
chemical background for
nanotechnology within 60 days subjective.

Toward the end of her stay in the clinic, Zaba had an understanding of
what the swarms of repair devices were doing to restore her spinal
cord, patiently teasing out where the nerves should be reconnected
across the gap,
replacing cell walls and myelin in the destroyed section, rebuilding
the shattered bone, muscle, and
connective tissue, and fishing out the bullet fragments down to single
atoms of lead. She
even had some understanding of how her mind was being supported in the
nanocomputers that were acting in
place of her very cold brain.

A few hours before her parents were to come on the last day, Zaba
warmed up her body under Suskulan's guidance. Her consciousness was
continuous as the reactivated brain cells took over from the
slowed-down swarm of
nanocomputers that had been simulating them. The support and
information umbilical connections
withdrew, and the holes in her skin closed seamlessly as Zaba started
breathing for the first
time in 9 days.

She sat up and coughed a few times. Her physical body was different
from what she had experienced for the past subjective 90 days. Better?
Worse? She could not decide
