Human progress can be seen as a series of advances, each advance being a new form of stratifying reality, separating the world into layers of abstraction. Think about this series of steps:
- Separation of sustenance from the process of production (when enough food excess was produced to sustain specialists, such as craftsmen, soldiers, artists, etc.) -- at some point, actually making food became abstracted away from having food.
- Separation of force (in the physical sense) from its use. At some point, task-specific force sources, such as horses, sails, and legs, became abstracted away -- when the steam engine was invented. Now you could just take an abstracted source of force, and plug it into your chosen task.
- Separation of information from its substrate. Thanks to Alan Turing, we know now how to abstract information, and information processes, away from the specific medium which carries them. The medium can be semiconductor or optical or mechanical, silicone or diamond or RNA, etc., but this doesn't materially affect the information process itself.
And the next step: - Separation of meaning from information.
Imagine a digitized picture of an apple. It consists of a series of numbers, a raw information stream; but with the right interpretation, we see it as an apple. What's more, we could have many different pictures, possessing different numeric content, yet all representing the same apple from different aspects, in different settings, under different lighting, etc. Furthermore, you could have different image encodings, even radically different sensory representations (e.g. a flat picture vs. a hologram vs. a verbal description vs. a direct neural feed). The same meaning is sustained by different information substrates, just as the same information substrates can be sustained by different physical media.
Of course the obvious answer is that our mind is what extracts the meaning from the data; but then the real question arises. Our mind, too, is an information process on neuronal substrate; but how does the mind, the meaning within it, emerge from information?
We have some inklings of that, but what we truly need is a radical advance, akin to what Alan Turing did, which would be a generalized theory of meaning and its relationship to information. We now see the next step, but we do not yet have the means of taking it. What would it mean to take it, though?
We understand the separation of information from matter, which is why we can conceptualize ourselves utillizing this abstraction, becoming substrate-independent information processes -- 'uploading' our minds into computing media and thus becoming pure information. If we can similarly comprehend the relationship between meaning and information, then I imagine the next step would be to abstract ourselves away from the information substrate, and become pure Meaning.
“In the beginning there was Word..."
If in transcending material substrate and becoming pure information we would become like olympic gods, able to bend reality to our desires, then in transcending information and becoming pure Meaning we would become like the biblical God, able to create reality out of raw thought and will.
