Our environment informs and shapes our behavior. Something geneticists call Epigenetics.
It then follows, that not just people, but also the machines and other things - toys, buildings, machines, caves, trees, etc., all play that role - being the environment that influences and defines us. "Defines us", because, unlike what most would think, even such subtle things as the choice of clothing and perfumes we wear or don't, likewise influence and shape our inner and projected identities. Thus, realizing as some of us have, life as it seems, is a huge game, in which, the identity of anyone, is mediated via symbolic cues chosen by the person - the symbols, despite being external, actually communicating something of what the inner person is - with or without their conscious awareness of it sometimes.
By framing our lives around technology, which as it currently is built, is inhuman, we risk absorbing much of the same inhumanness, in our behavior, and not just in interactions with machines, but with fellow humans and other entities as well.
Machines, just like the animate and innanimate objects we allow into our lives, become a part of us, and thus, whether we know it or not, they influence our behavior and state of mind.
A user with a sick computer, will likewise become sick.
A user with an out-dated computer, will likewise behave in an outdated manner.
A user with an insecure computer, will likewise be insecure.
A user with a cluttered computer, will likewise have a disorganized life.
A user with a powerful, speedy machine, will likewise be potent.
Essentially, we are living as cyborgs - partially human/bio, partially machine/metal, but the level of integration varies, based on the dependence of the human upon the machine, and also on how intimately connected, the two are. It's not so far fetched, to imagine a near future in which the machines start to become literal extensions of our bodies as well - where metal and body start to merge. Actually, this has already happened, with prosthetics in particular!
Oh, how we should have to ask the questions:
Do we wish to keep these bodies, or not?
Does being human have anything to do with our looks, or could we become something else entirely?
And what of our ultimate purpose? Isn't it already obvious?
To nurture and evolve our best, so when the time comes to propagate elsewhere, as the only logical thing to do in a system that is definitely bound to self-extinguish, we have our best available, to keep the species, or what'll be left of it, alive and capable of continuing our destiny, unto the great unknowns yet to come.
Thus Must I admit this; I have seen upon this truth, and can not in anyway, keep it within my chest, without bringing this light unto you all. That's my role - share that which I've seen.
