How do we all earn money these days? I do some manual work, but mostly, it is via thought and creativity, isn't it? Hence, once I have 20 machines that are as smart as me, yet 100 times faster, I will be able to design 10000 web pages an hour in my sleep, for a near-zero cost (after capital investment). But I can't get rich, since so can everyone else. And if I offer my services for 1 penny a page, there will still be lots of people doing it for free!
At this stage, money is worth nothing any more, for any job that doesn't involve manipulation of actual things. Those jobs that do involve moving things, they will fall as soon as a robot is mass-produced to do that job (or, indeed, almost any job)
you are assuming that in 20-50 years people will still be access the net externally
if you can digitize your consciousness that AI in the net will be you!
then identity theft will take on a whole new meaning anyone could potentially clone you and download your consciousness into that clone and murder you
this i think is why murder is forbade by the commandments. amoung other things killing without cause is wrong, which brings up another commandment abouts creating likenesses of a human, cloning is then forbade, if you then duplicate someone who should have the right to live?
the clone or the of woman born man?
the clone would be healthier have a cleaner mind to think with and possibly would be better for society if before its mind is "installed" its given muscle trainging like an athlete and mind training like a mathematician. as long as the brain graft takes that cloned body would be many times more important than the bacteria and virus infested ultimately corrupt human.
another question is if you upload yourself into the net, will you exist at once in your body and the net? able to mingles consciouness seemlessly through that link? can that consciousness be transferred such that the human mind transfers from the human body to the cloned body intact, without destroying the old person... i'd hate to think that cloning technology would mean that each clone once grafted with the mind of a human is independant from the original, instead you'd get the original transferring to the new cloned body, saying yes its me i'm here i made the leap, kill my old body.
what if thats the way it works but you are still in the old body? what happens if the instant the link is severed that the start growing apart becoming individuals? could the old body then rightly be killed? or should it be retired until it dies of natural causes?
for now unfortunately i think even if the human once link through a machine to its clones brain as soon as the link is severed the humans consciouness will remain in the old body, making killing it a sin against god. you'd be duplicating a human but once the link is severed they become two living breathing individuals.
the moment the clone takes its first deep breath after a graft and proclaims that body to be the property of the original bodies mind, will be as important and earth shattering as the harnessing of fire. we will have cheated death, in the last moment of life a human could connect himself to the net and plug into a reserve clone and upload himself, before the spark of life leaves him. unless that person had retained a backup image with genetic savings and clone where at the moment of death a clone is activated based on the last backup, which could be done as a streaming process, requiring the human to be connected to the net at all times. taking yourself off the net would in itself be a little death.
the mind is the process of a functioning brain
then linking the mind through a clone prolly by means of a direct brain to brain link (think siamese organism linked at the based of the skull, unable to see its other half), then systematically shutting down the original brain or all at once will mean the mind will find the new brain and begin functioning through both brains at once, four eyes, four arms two mouths, 40 digits.
once the mind in the clone signals the ok (that the conscious mind have made all the appropriate links to the new bodies systems), something like a day or more into the merging grafting process the old brain and body are shut down with sedatives, meaning the clone brain would take precedence.
or if the process is meant to be only a backup, with the clone living somewhere in the desert while the original goes thrill seeking, then occassionally that clone will have to be updated, the merging process beginning again. the original then would be updated with all the dull things its clone has been doing and the clone updated with the persons life experiences for the last little while.
a direct neural link may not be intirely necessary, so long as the throughput over a network link is fast enough to handle the throuput of millions or billions of neurons at once. brain to brain merging thus might require a computer assisted go between, mitigating the flow normalizing it for the recieving brain. thus gigabit throughput and gigabit processing, but that gigabit processing has to have gigabits of ram to hold the transitioning consciouness both live and in a buffer.
