Human transcedence of biology implies, requires and is based, to a great extent, on the connection of intelligence, both biological (reminiscent and not very significant) and machine (absolutely dominant) intelligence.
It is hard to imagine individual subjectivity (subjectivity being a fundamental requisite of consciousness) and, consequently, diversity in an intelligence-connected world.
It is easier to imagine finding subjectivity at the beginning of the interconnection, when software efficiency is not perfect, when connections are not absolute and permanent, and while biological participation in total-connected intelligence is still relevant. During these preliminary times of interconnection there will still be different instances (consciences) capable of switching the connection on/off at will (meaning that there still exist different wills), but as intelligences merge and tend to unify that capacity will certainly diminish, probably to the point of disappearance.
It is even imaginable that such forecast of intelligence merging and unification will occur sooner than later.
By the way, will seems a better marker of consciousness to me, at least of 'significant consciousness', than subjectivity.
This brings me to the conclusion of my previous post (Intelligence unity should only coincide with saturation, excuse the auto reference, I have a one-track mind) and to the dominant Pyramid principle of power (not to be confused with Barbara Minton's Pyramid principle for logical thinking and efficient presentations)... but I'll deal with that some other time... I hope.
As you can easily realize, the role of the will also plays a big part in all these considerations, both for strategy planning and for consequence managing purposes, and I should evolve on my idea of its significance... but, as before, it will have to wait for a better time, that I hope will come soon.
