Conscious Cybernaut
I don't design myself. I evolve from countless interactions, of which the conscious mind is but the emerged part, that neither designs nor builds itself nor the rest of me. At best, it might steer me towards improvement - but the direction it steers won't be improvement if it is blind of who I am, where I am, what are the obstacles, what are my assets, and what maintenance is required.
The rationalist hubris of total design is often blindness that cripples the actual use of reason. On the opposite, denial of the importance design in steering is the rejection of reason and groveling in mere animality. Be yourself today. Fully.
