Immortality: Who Wants To Live Forever? Part Two

“Nothing is certain but death and taxes”, so the saying goes, and while much has been written about taxes, death, or the lack of death, the latter is my topic under consideration. The question I pose is, can technology deliver on what religion promises, but probably can’t deliver on - that is to say, the promise of life eternal.

Continued from yesterday’s blog…

Apart from the immortality question, let’s say you have an intense personal desire to have a career exploring the planet Jupiter – not via telescope, but in person. Today, for various reasons, your prospects are bugger-all. There’s no way to get you there at the moment, and you couldn’t survive the hostile environment even if you did. There’s no part of your organic body that would survive the Jovian (Jupiter’s) environment.  And if you wanted to explore, in person, extra-solar ‘Jupiters’,  in addition to inherent hostile environments, you wouldn’t survive the time frames necessary to get you to them which would require interstellar travel, travel to be measured in tens to hundreds of thousands of years at present, even extrapolated advances in spacecraft velocities in the near to midterm future.

So, even a combination of your organic biology coupled with some machine technology (you becoming a cybernetic bio-mechanical hybrid) wouldn’t ultimately help your goal. What would work would be an entirely technological or mechanical ‘organism’ – a robot with artificial intelligence – one that could survive the lengthy journey times and the hostile environments. But that doesn’t do you (or more to the point your mind that’s within you) any good – unless you became that robot! However, one needs then to get the relevant organic parts of you – your mind or your brain - into an inorganic form.

Just as it’s currently possible for one to transfer or download the contents of one computer into another computer, and just as your brain (which contains your mind) is an advanced type of computer – it’s your mind’s software that controls the rest of you - so too might it be eventually possible for your organic mind-within-your-brain to be downloaded into a nuts-and-bolts computer which could then be merged with an appropriate mechanical body or some other technology specifically designed to achieve a particular goal that’s unachievable by actual  flesh and blood. Examples are exploring Jupiter, space travel to distant stars and solar systems, or undersea exploration. You cannot, unaided, dive to the depths where RMS Titanic rests of the bottom of the Atlantic. If your mind however was somehow contained within a silicon and steel robot, well exploring the oceanographic depths would be easy. Robotic probes have explored the Titanic and the deepest of the deep parts of the ocean.

The upshot is that if your mind, the inner “you”, were part and parcel of residing inside an inorganic body, given that inorganic materials last a hell of a lot longer than organic bodies, then you’ve achieved quasi-immortality!  That’s ditto the case in that when your mind becomes the software in an inorganic computer. That software can later be transferred to another computer and then another and then another – right on down the line. That can also lead to lots of copies of your mind being around. Not only quasi-immortality, but cloning as well!

Using nanotechnology, building from the ground up, atom by atom, tiny but useful machines/things is a

current rapidly emerging technology in our 21^st Century. Fast forward to the far future – if one has, down to the last detail, a blueprint for a living thing, then even that living thing could be created, from the ground up, atom by atom, using nanotechnology techniques, again and again and again – all identical. That living thing could be the physical you combined with the inner you – your mind - a being identical to whatever the pre-existing you was. Immortality! [As an aside, this is the way, atom by atom, that organic bodies are naturally constructed. Our food, air, water, etc. are broken down and recombined into organic compounds, bio-chemicals and so on up the chain through to cells and tissues and organs, etc.]

Of course such complicated nanotechnology may well be many centuries (if ever) away before this version of immortality is even a remote possibility. But, who knows what advancements might be possible that far ahead?

That said, it’s therefore possible that very advanced extraterrestrial intelligences have already achieved, if not immortality, then at least something approaching it. Such a civilization would have no difficulty, if so inclined, in exploring, even colonizing the galaxy in fairly short order – several millions of years at most, even at sub-light speeds. That’s a small fraction of the age of our galaxy. Extraterrestrials can colonize the galaxy akin to how humans have colonized Planet Earth – it doesn’t take that long relative to the age of the object – galaxy or Planet Earth – being colonized.

Quite apart from achieving immortality through silicon and steel, or nanotechnology, you know there is no law of nature that states you must die after so many days; after three score and ten years; after so many heartbeats; after so many cell divisions; after so much calorie intake; after so much whatever. Therefore, perhaps you might be justified in firmly believing that no matter what, you will always wake up the next morning. You are so convinced of that that you have never even remotely contemplated making out a will, or buying a graveyard plot, or making any sorts of arrangements post your death –cause it ain’t gonna happen! That’s the power of positive thinking as it were! Of course that leads to the converse, perhaps if you do acknowledge that there’s no uncertainty when it comes to your death, you’ve sealed your own fate! Once you accept that you will die, you will indeed. Of course it may not matter one bit what you firmly believe or refuse to believe in or acknowledge – like your own croaking. I assume it doesn’t matter since I suspect over time there have been lots of individuals who have denied death’s inevitability, but nevertheless, are now stone cold dead.

Of course in one sense we all achieve a form of immortality. Some of our atoms and molecules that made us up will eventually recycle and become incorporated into new life forms - maybe as bacteria, or plants or bugs or maybe a part of another person. The heart may not go on, but the atomic bits and pieces will. Perhaps after billions of years, after our sun and solar system are no more, some of the fundamental particles that make you, you, might find its way across the cosmos to eventually become incorporated into some extraterrestrial life form! The reverse might also be true – molecular bits of you might once, eons ago, have been part of an alien organism.
