smart dust

if countries don't want 

self replicating molecular machines 

and/or self replicating nano machines 

to be officially allowed in the civilian healthcare sector 

because of risks of using powerful technologies 

and because of national security implications 

then non replicating molecular machines 

would be less of a powerful technology risk 

and would be less of a national security implication 

or else then maybe smart dust 

consisting of micrometer particles with nanometer size transistors 

could officially be used in civilian healthcare 

for brain and nerve implants in patients with brain / nerve injuries 

so that those patients possibly could be able 

to regain some brain function 

and/or some brain control of body 

and/or some brain control of prosthesis 

the smart dust would be injected into the blood stream 

and travel to the brain cells in the brain and attach to them 

the smart dust particles would communicate with the brain cell 

that they are attached to 

and also wirelessly communicate with other smart dust particles 

that are atrached to other brain cells 

this would create a second neural net in the brain 

that would connect brain cells 

that previously were disconnected because of injuries 

the smart dust particles would wirelessly get energy 

from hardware in a hat that the patient wears 

production of nanometer transistors is relatively easy 

in the civilian commercial sector 

but making the chips micrometer size could be a challenge 

the problems would be 

how the smart dust particles would navigate and move 

in the blood stream and in the brain to each brain cell 

if smart dust is not viable because of slow technological progress 

in the civilian healthcare sector 

then aggressive implementation of experimental gene therapies 

could be another path forward 

but a combination of smart dust and gene therapies would be better 

even better would be non replicating molecular machines 

in combination with gene therapies 

and best of all would be self replicating nano machines
