[Welcome to Thoughtful Tuesday! You know the format by now: I rant, I rave, I reveal thoughts that bounce around in my head that don't necessarily make sense yet, but may do with a little more thought... This week, a particularly meaty subject that pops up on the blog fairly regularly: Transhumanism.]

It’s a long word that sounds a lot more complex than it actually is but the most important part of its definition, as defined by the Transhumanism Declaration (2002), is thus:

Humanity will be radically changed by technology in the future. We [Humanity+] foresee the feasibility of redesigning the human condition, including such parameters as the inevitability of aging, limitations on human and artificial intellects, unchosen psychology, suffering, and our confinement to the planet Earth.

I know. This is serious business! But let’s not get bogged down with long, complex words and ideology. Transhumanism is, basically, the next step in human evolution; in enlightenment.

For the longest time imaginable we’ve been limited by our body. We push its boundaries, we perform feats of extraordinary endurance and power, but at the end of the day it is limited. Eventually, something snaps: a bone breaks, we grow senile — and, sooner or later, we die.

Progress in the areas of humanism and enlightenment are all about prolonging (and improving!) our mental, physical and and spiritual well-being. Thus, that’s exactly what transhumanism is all about: we’ve reached our current, imposed-by-our-physical-body limits; now it’s time to let technology do its thing. It’s time to modify our bodies to take us to the next level!

Let me just throw out some possible modifications (upgrades!) that are covered by transhumanism:

• Biotechnological implants/replacements. Strength, speed, eyesight and endurance limits/thresholds raised way beyond current human bottlenecks.
• Modification of our genetic makeup. This is the one that’s currently under scrutiny from the media. This area deals with the modification of ourselves (or our progeny) to make us inherently more resistant or to damage/pathology. Immunity to disease, removal of short-sight — that kind of thing (though obviously ‘designer babies’ with blue eyes and perfect, beautiful appearance would be quite popular…)
• Prevent ageing (aging). Transhumanism covers the slowing of aging, or even prolonging life until we’re effectively immortal (Who wants to live forever?). Cryogenics also come into play here, though the real ‘philosopher’s stone’ is immortality, of course. This will probably take a biotechnological form — replacement organs, repairing cellular damage, etc.
• A lot more that hasn’t been invented yet…! As a general rule, most things that are speculated or appear in sci-fi novels later appear in real life. We can expect to see some really crazy technologies appear in the future. Artificial intelligence (think Terminator), proper virtual reality (think holodeck in Star Trek) and my favourite — mind-uploading, ala The Matrix: ‘I know kung fu…’

Obviously, along with such awesome abilities come a seriously large number of issues, most of which are of an ethical nature:

You can’t play God!

You’ll turn… into a Frankenstein!

Perhaps it is the existential issue that is most worrisome: When do we stop being human? It’s certainly not when we replace the heart or any of the limbs. It’s the brain, right…? Or is it? How do we know until we try? Do we really trust Bible-thumpers that, let’s face it, know absolutely nothing about cybernetics? That’s why we’re afraid: we have absolutely no idea what we’re getting into. But if history has shown us anything, is it ever beneficial to shy away from, instead of facing, the oncoming torrent of technological progress?

As with any technology there are good and bad uses — as to what defines good or bad, I won’t attempt to state — using transhumanist technology is a two-edged blade. You could enhance only yourself or the genetics of your progeny — a selfish act? — or, with the same technology, you could genetically modify those living in sub-Saharan Africa so that they could live without food.

It’s not guns that kill people…

The thing is, I could go into the ethical repercussions, and whether transhumanism should be allowed or not… but… really, it’s inconsequential. We’re going to do it anyway. Of course there will be devout naysayers — sociologists, psychologists, humanitarians, Christians — (the whole gamut!) — but there always is. The truth — the technology – will out. You can’t stop everyone from kite-flying in thunderstorms.

There is something about technology. It’s all there, just waiting to be discovered. As I’ve already covered, we really like turning over stones. We really like uncovering mysteries. This is the biggest of them by far. What makes us human?

This is going to happen in the next decade, by the way. If you have moral, ethical or philosophical disagreements, you probably want to settle them now, before upgrades for your bionic eyes and ears start appearing in the supermarket.

Healthcare (or health care if you’re a colonial) means different things to different people. Depending on where you live, your background and your income, it might be synonymous with either insurance or the treatment of illness — and in some cases, it can even mean the public health of a nation or zone.

It’s important to think about these three things as separate entities: despite prevailing culture, you can’t mix up health insurance with the actual treatment of illness — they can both exist, but must be independent of each other. Health insurance, in countries without publicly-funded systems, is simply the way health care is paid for. In countries with ‘universal coverage’ like the UK, health insurance is used to pay for private care, or ‘complementary medicine’ (i.e. new/weird science). Public health is the overarching effort to improve health through improved knowledge and awareness, such as eating five portions of vegetables a day, ‘got milk?’, and so on.

Now, with that out of the way, let’s tuck in.

Healthcare is vital in the most true sense of the word. Without it we would die, immediately in a blaze of flame, or in a laboriously drawn-out fashion — it doesn’t matter: health care stops us from dying. Healthcare is so vital (there’s that word again) that about 10% of a Western nation’s GDP — 10% of its entire income — is spent on it. Some would argue that’s a small price to pay, for longevity of life. By comparison, most nations spend between 2 and 4% of their GDP on military/defence, and education comes in at about 5-7% of a nation’s GDP. So, as you can see, and have no doubt heard from Obama, health care is the biggest human issue.

But it’s all a damn mess; a horrible void of misunderstanding and overspending. And it all derives from a ‘knowledge gap’, between the doctor and the patient. The same can be said for most professions, but with healthcare the distance is most significant. Even if you don’t know the basic fundamentals of household plumbing, or how data traverses the Internet, you can still sleep soundly at night. But what if you’ve just been told you have cancer? Or that you’re being treated with Interferon beta-1a? You get a little jumpy, a little nervous — because you might die.

If we’ve learnt anything about the human body in the last 100 years, it’s that we should fear the inevitable onrush of death. Somewhere along the line we made the switch from ‘the most rugged and tenacious mammal on the planet’ to ‘wuss’. We used to live — and die. Now there are many more steps on the meter: alive, stressed, ill, broken, comatose, dead — and thousands more slotted in between.

Something doesn’t make sense. Why are we more afraid of our health now than 100 years ago? I’m not saying no one cared about death back then — people certainly put a lot of effort into making sure things were left tidy, and that the relevant gods would receive them into the afterlife — but it was just part of living. I think it has something to do with knowledge, and thus certainty and confidence. If you’re brought up with the knowledge that you will die by the age of 60 and you will die if you mistreat your body, that’s some stable knowledge that you can operate with. You can go out and live life.

What do we know about life and death today? Do you know how long you will live for, or if the quality of your life is assured? If I eat this burger, will it shorten my life — does that even matter? Should I be worried about senility, or will biotechnology/biopharmacy save me from that feckless fate?

It’s pretty weird to be confused about your own mortality, eh? A long, healthy life is the single most desirable wish — yet it is the one thing we are most uncertain about! I want to tie this in to the downfall of faith/belief and the rescinded promise of eternal (after)life, but I’m not sure I can yet — but it would make sense that, up until the last century, death was just been a temporary setback… but now it’s personal. (I kid, I kid, but you get the idea.)

To fix this problem, we need to close the gap between bleeding-edge research, the doctors, and us. We have to know more about our bodies and what they’re capable of; education obviously ties in at this point. I think we’re regularly reminded, and amazed, by what humans are capable of and how resilient we are — but at the same time, we have never been more aware of just how defenceless we ultimately are. Back then, we just died. No one knew why, we just died.

Now we die of cancer, heart disease, sclerosis, embolism — all invisible, all able to pounce at any time with little or no warning. But they’ve always been there, just like gravity or hydrogen. If we want to live long and healthy lives, we must teach about healthcare in schools. We must learn more about the body than the knee bone’s connection to the thigh bone, more than veins and arteries — like ancient Rome and Athens, education must be contemporary and hot on the heels of research.
