"I think therefore I am". Descartes, okay.
This statement does create the question if mental autonomy is a precondition for scientific cognition or -the other way round- if an increasing scientific cognition leads to/creates mental autonomy.
I think it works perfectly in both ways.
Man already owns this mental autonomy (at least...some of us...

)It makes him explore and work and build new knowledge in science and technology.
So he creates machines. And he goes on exploring and it comes the time when he has gained enough knowledge to be able to teach the machines to think and to feel - which is not unlikely, I think, when you consider thoughts and emotions as "ordinary" chemical processes (like breathing or transferring food into energy)that just hasn´t been completely explained yet.
So -coming back on Descartes- the second assumption is working now. By been taught thinking and feeling the machines begin to develop their own mental autonomy.
And now we don´t have another choice than "considering machines a conscious entity" I suppose.
We cannot "linguistically differentiate a person from a computer" anymore.
Some might say, of course we can, from a material point of view.
Yes, indeed, a computer has a different physical, bodily form than a human being, but I don´t think that´s what counts in this case.
More important is, that humans and machines are equal on a mental level then.
I often feel that people haven´t made up their minds yet if that´s gonna be a reason to chant in happiness or to be scared. Maybe I haven´t, too. Time will tell.
I could think about things like that for hours (and I often do, when I find the time), and I love to discuss them, but unfortunately I hardly meet people in my life who think in a similar way, hehe...
so I just wrote some of my strange thoughts down. Don´t care.
I don´t want to bother you any longer. I was just somehow "thinking aloud", inspired by listening to "The Learning" on headphones (Very intense! Damn!!).
Maybe my point of view seemed confusing or illogical to you, I´m afraid things would´ve been easier for me to express in my mother tongue. But who cares, it´s ONE way of thinking, so nobody needs to feel offended (just in case...

)
But now I *cough* have to concentrate on work again *cough*, thoughts like the ones above are not useful when you´re sitting in an office trying to construct drilling machines...
