This may be the only way humanity will be able to explore space, to become more metal than flesh.
The thought of downloading a human consciousness into a robot. Obviously its sci fi thinking but there are certainly some major advantages for space flight. For instance, no need to think about hibernation for space flight when a robot could be powered down for decades or centuries.
It also leads me to some ethical issues. While the human grows old and dies on earth, the robot with all the human’s thoughts, memories, emotions, etc continues on. Does it have a soul?
And then there are other interesting things worth ponderin. For instance, as the robot carrying the human consciousness does its thing, it has new experiences and learns new things. Eventually it would begin to diverge from its human counterpart and start to become a different personality. If you really want to get extreme with that thinking, imagine if the robot could produce new robots and download its consciousness and those would further diverge from the original human ancestor.
Just mind wandering that I do sometimes. Kinda wish I had writing skills to put that sort of thing into book form.
