Seeing the above links got me thinking about
technology and how it can be used to help us, not harm us.   The quote
from the movie "The Rock" came to mind too, when Dr. Stanley Goodspeed
(played by Nicholas Cage) is asked what he knows about VX gas he says
soberly "it’s one of those things we wish we could un-invent."   But
does technology always result in something horrible for the human
race?    That’s a rhetorical question of course, since we know it
doesn’t (anti-lock brakes, the MRI, and penicillin come to mind)

What’s really fascinating here is not some bizarre borg-like development of humans, but, the actual good use of technology to help
people who truly need it.   In this case, soldiers, both men and women,
sent to war and, in the midst,  facing the effects of having a limb
destroyed or blown off as a result.  The trauma must be incredible,
both physically and psychologically.   The co-developments in robotics
and prosthetics, looks as though it’s moving to a new phase where those
damaged could really be helped, in a big way.
