Dimension, or why 3D printers and artificial intelligence do not take over the world

    Well, they will more accurately capture it - but not now. I'm not a cynic at all - I am sincerely delighted with what modern technologies are capable of. But when I hear the confident and visionary “3D printers will change our lives - you can print anything on them right at home” or “after 5-10-15 years, artificial intelligence will become equal to humans ...” I get cheekbones from bewilderment.


    But what about the dimension? Dimension ... it spoils everything.

    About evil infinity and definitions

    The guinea pig. Firstly, not a sea, and secondly, not a pig ...

    Remember at school geometry lessons? How many points in a segment? Infinitely. And how many pieces are squared? Endless too. And then how many points are squared? What, infinity again? This is already some kind of evil infinity, infinity of the second order ... thank God in the real world, to draw a tolerable segment you do not need to draw points endlessly - a qualitative leap occurs quite quickly - and the set of points subjectively turns into a completely tolerable line.

    But in order to draw a square we will have to make a qualitative leap again - after all, how many do not push the dots into a segment, it will not become a square. Each new dimension requires its own qualitative transition.

    The confusion, as always, begins with incorrect definitions - a 3D printer is not a printer (it doesn’t make any “prints” and images), and in general it’s not 3D. If you simplify the scheme of the printer, it most closely resembles the “concrete pouring machine” with which modern houses are built. He creeps back and forth, squeezing out the sausages of the congealing mass.

    About complexity and usefulness

    Dad, and who will take whom - an elephant whale or a whale elephant?

    To and fro - these are two whole dimensions that require high-quality transitions - the ability to move very discreetly along two axes. In this sense, 3D is no better than regular Laserjeta. But unlike a commonplace printer, it can move in another dimension - up and down. This truth does not mean that the printer can print an arbitrary point in space (evil gravity does not allow). So far, each element of the printed design must be securely attached to the footboard, so the third dimension is more experimental and nothing good comes out without finalizing the resulting product with a file. If you do not believe me, try printing a baby rattle and tell us how you did it.

    It would seem that a 3D printer should logically be an order of magnitude more complex than a color photo printer. But nothing of the sort - a regular color printer has at least three more color space dimensions. And this gives him the necessary versatility, allowing you to print almost any image. The path from the first black-and-white printer to a full-color one took a modest 30 years, and this despite the fact that the theory of printing and color theory are well developed. 3D printer as a printing device is much easier than a good color photo printer. And the only reason why he did not appear much earlier is because of his economic inexpediency.

    About dimension

    Which one do you want to be smart or beautiful?

    What way does the printer need to go to take over the world? That it really became possible to print the necessary things on it. Let's put the dimensions that exist in the world of real things. I understand that the list is not accurate, but even offhand:

    • Hardness (soft - hard)
    • Density (Light - Heavy)
    • Plasticity (plastic - elastic)
    • Conductivity (dielectric - conductor)
    • Hue (Red - Purple)
    • Saturation (colorless - color)
    • Brightness (more precisely reflectivity) (black - bright)
    • Thermal conductivity (I can’t even pick up words)
    • Chemical activity (inert - active)
    • ...

    And if for example you are planning to print food, then add more edibility, humidity, acidity, salinity, bitterness, meatiness .... And we did not affect the aroma ...

    About life

    The inhabitants always vulgarize the most beautiful ideas.

    Imagine - Saturday, morning. Children call you to play table tennis with them. You quickly change into a tracksuit, grab the net and rackets - but the trouble is, the dog gnawed all the balls. Run to the store? Nonsense, you have a 3D printer! All you have to do is print a couple of balls. The simplest elastic light white is almost an ideal sphere, it’s not a heavy solid “some kind of edr there” with a cool logo ... (oh, it's a golf ball)

    Five minutes of searching the Internet and you have already downloaded a great model. The printer rumbles for a couple of minutes, processing the order - and lo and behold! You have a crooked monster in your hands that jumps poorly and weighs like a sinker ...

    Thank God that retrograde children ordered everything in an online store and the delivery drone is already neatly unloading the parcel in the center of the lawn ...

    About progress

    At the time when spaceships ...

    The thing is that your printer must have a high resolution for each dimension, so high that the quantity turns into quality. I have no idea how this problem will be solved - the only thing that comes to my mind is the creation of material with the specified chemical and physical properties at the required point in space (a common thing for the Demiurg-2200 series printers is after all two megawatt thermonuclear power supply and Yahva Inside electronic tunneling arm on board)

    I am an optimist - and I believe that someday it will be so. But for now, it remains for us to admire the technological progress, watching how sausages of molten plastic fall onto the substrate with jewelry accuracy.

    Well, where does the artificial intelligence? And all the same dimension ... The current mind is 7 billion individuals, 500 million years of evolution, billions of neurons. And each of them has thousands of arbitrary connections (three-dimensional dimension of the volumetric brain, instead of a one-dimensional code of zeros and ones). And over all this wealth, signals of many types run differently processed and interpreted in different chemical environments (oh, these pranksters are mu-opiates, endorphins and oxytocins ...) So do not expect a real mind in the near future. Although who knows, where is the subjective border of the transition of quantity into quality ...
