[ExI] What % of H+ = Electromechanical Devices

[natasha at natasha.cc]

In distinguishing the use of the term cyborg and the term transhuman  
in regards to human enhancement, here are a few questions:

In your estimation, what percentage of human enhancement options are  
based within the domain of electromechanical devices?

For example, if human enhancement would be largely the result of  
bio-genetic engineering, stem cell cloning, prosthetic synthetic body  
parts, robotics+AI/AGI, pharmacology, and nanomedicine's nanocytes and  
nanorobots, what domains would you suggest these (and other  
technologies/sciences not mentioned) are located, other than  
electromechanical devices?

If you consider human enhancement to include whole brain emulation, do  
you consider this to be strictly within the domain of cybernetics'  
electromechanical devices?  If so, why and if not, why?

Any and all other comments relating to this are welcome.

Many thanks,
Natasha
