The premise
What would be the consequences of transferring the consciousness of a middle-aged person to a mechanical object or device (such as a robot), as opposed to another biological body?
Specifically, self awareness, inner thoughts, complete memories (implying continuity of identity), to be transferred to a machine which could function and have abilities completely different than those of a human body, and well beyond its limitations, including infinite existence
The object would be capable of storing new memories and experiences (including the transfer itself), be able to learn new things continuously, and at least match our brain's complexity (~85 billion neurons and all current synapses) including ability to imagine, and "forget" or filter memories deemed unimportant or not useful for a given situation.
This would mean that the individual would also be able to have intuition, empathy, be inspired, ecstatic, impressed, philosophical, hopeful, but also disappointed, sad, devastated, depressed, cold, or desperate, like any other human being. Another aspect: a third of our days are spent sleeping, so this will automatically increase the accumulated knowledge/experience without the need for sleep and its by-process - dream
To eliminate a controversial subject: it is given that the transfer would be instantaneous and it would terminate the biological body as soon as it is completed, and biological death is perceived by the new consciousness - observing your self from two different perspectives simultaneously is off-topic, as it implies a new consciousness, regardless of how exact the copy of "history" and personality is. The continuation of identity takes place when all sensory inputs of the new object become active
The question(s)
How can the consciousness safely adjust (psychologically) to the surrounding reality, and its own existence in general, like suppressing subconscious instincts - breathing, hunger, thirst, procreation (sex drive), and accepting the concept of endless life with overwhelming possibilities, compared to the previous mindset of embedded limitations - relatively fragile body, ever-present danger of sickness with pain, and inevitable end of life? (It must cope one way or another, but to eventually emerge without unbearable emotional distress and psychological damage)
If this adjustment is possible, is eternal existence truly desirable - with the same personality and self-accepted behaviors, reactions, and subjective defects? What would be the infinite drive or motivation for existence: fears, passions, unhappiness balanced against new notions of satisfaction or joy, abstract appreciation for new forms of art or "beauty". Or would feelings and emotions become irrelevant over time? How would "good" and "evil" transform or be perceived? What is the ultimate benefit of immortality once an individual achieves their full potential? Would a "full potential" be achieved?
I guess, this transfer would mean a fundamental change in mentality, from the known evolutionary process of genetic transfer, to continual self evolution and improvement, ... but to what end - why do we desire to live forever? Why do we want to be perpetually aware, when we don't know the meaning of our existence as it is now (minimalist suffering), contentment?
Ps. Our minds can't hope to fathom the concept of infinity - no beginning and no end, EVER ! - so we just gave it a label, not to deal with its disturbing, unimaginable magnitude (for both time and space), never mind "looking back on your life after a few trillion years, as if it were a second ago"
