Printed books existed nearly 600 years before Gutenberg’s Bible

That is, his key innovation was a way to mass-produce the characters (the movable type) which could then be arranged to mass-produce the printed pages.
First, individual characters were carved from steel (each taking about a day to make). This was the only part of the process done "by hand". Every other element of the process was produced through some form of (repeatable/arrangeable) transfer of shape/information.
The master characters were hammered into brass to create a mold which could then be reused to cast multiple copies of a character. Each page had thousands of characters and Gutenberg's shop had multiple presses going at a time, so they needed lots of these characters on hand (50,000 is a conservative estimate).
The masters could also be easily transported to another city. These masters (plus raw materials of course) were all that was needed to set up a new print shop. This enabled the printing press technology to quickly spread throughout Europe.
I think it's a good analogy for the power of software :)

instance / class / metaclass / ()
instance / model / metamodel / () -- very redundant.
value / type / kind / ()
machine / vm / utm / ()
() denotes the closed loop where you don't need another layer.anybody has a theory that explains this trait ?
If we were being precise, we would explicitly denote the level at which we were working. However, we tend not to do so for two reasons: first, that we rarely work with n-meta things for high n; and second, that being explicit is just plain unwieldy.
It’s for the same reason that we follow line, square, and cube with 4-cube, 5-cube, &c.
however, once you hit that second level of abstraction, you have almost invariably added enough flexibility that the range of templates your template-maker can make includes templates for other template makers. that is, it's not just a quirk of linguistics that a meta-meta-template-maker is called a meta-template-maker, they really do tend to be objects on the same level of abstraction and flexibility.
Instance ::= 0
Meta(X) ::= Succ(X)
But it’s much more convenient to define meta- recursively: Instance ::= 0
Meta(X) ::= Succ(X)
| Meta(Succ(X))
In both cases, we have an arbitrary designation: Class ::= Succ(Instance)
That kind of redundancy is a linguistic artifact, not a deeply meaningful one.It’s not the case that reaching the second level of abstraction necessarily results in enough flexibility to make the inductive step. As a counterexample, consider C macros, which only add one meta- because they are only expanded once. Lisp macros, on the other hand, are expanded until a fixed point is found. That’s why Lisp macros are Turing-complete while the C preprocessor is only a pushdown automaton.
Common Lisp macro bodies are written in Common Lisp, i.e. written in a Turing-complete language — they would still be Turing-complete even if we wrote them in the subset Lisp-without-macros. The C preprocessor, on the other hand, does not invoke a Turing-complete language to compute a macro's expansion.
Of course, abjads and syllabaries are as common (and about as modular) as alphabets, so it’s likely that we would have been fine either way. Still, it’s interesting to think of what Europe would be like if the predominant script were semantophonetic like Chinese. Oddly enough, the main reason that phonemic scripts exist is precisely because languages tend to be non-isolating—in other words, modularity in a language leads to non-modularity in its orthography, and vice versa.
Before the Romans, the Greek and Phonecian writing systems (and derivitives) were taking hold, and more complex scripts (like Chinese logograms) had never simply never been common near Europe, with the single notable exception of Egyptian heiroglyphs (which had complex logograms, but could equally be used with simpler phonetic characters).
Gutenberg's type metal was also considerably harder than (say) pure lead, which made it possible to print thousands of impressions from one setup.

Woodblock printing is ancient, mostly used for religious texts but requires very little infrastructure. Obviously not suitable for small printing runs, as the entire block has to be carved at once.
Bi Sheng invented movable type using porcelain characters. But Chinese is fantastically ill suited to that sort of printing; it was viewed historically as a novelty and not used basically at all. He decamped to Korea where he found a more receptive audience, IIRC.
Gutenburg's type alloy and the casting process were the real core of the innovation; the rest of the technology existed, but wasn't compelling without the ability to mass produce characters and with a reliable type alloy.
Oddly enough and for reasons I don't fully understand, woodblock printing didn't take off in Europe until after moveable type came in; mostly for illustrations, IIRC.

However, Gutenberg's was far superior because the press could be altered, the chinese press was carved in wood and could not be modified.
but isn't it more work to hide the content from js-disabled-browsers? so why do it?
It's not about getting there first, it's about doing it well. For many the same reasons everyone assumes Edison invented lightbulbs many assume Gutenberg invented printed books. Neither invented the core concept, they just refined it down into what it needed to be to be marketable. Gutenberg disrupted an entire industry not by printing the books but, as others have mentioned, by designing a system that was relatively cheap and more reliable compared to the previous systems.
Although if you want to talk about truly contentious tech. history and marketable success you'd have to head to photography.

One discussion topic could be why Gutenberg's press had the explosive effect it had in Europe and not in China? Tyndale smuggling his printed bibles to England may be mentioned.
Another, harder discussion, would be why such topics, i.e. "we invented X hundreds of years before you!" still entice people from the "East" and cause resentment.
Not able to do that on this board, let me give you the following lengthy quotation instead, from Orhan Pamuk's The Black Book, (for me) his best work so far [I mostly used Maureen Freely's bad translation, made a few changes]. This is one of the best novels I know trying to analyze the "East is East, and West is West, and never the twain shall meet", which in a number of very few countries (Turkey foremost, but Russia, too, and some Balkan countries perhaps) has an indelible effect on daily life.

Whenever I venture into the endless saga about what the West stole from the East and East from the West, I think this: If this realm of dreams we call the world is but a house we roam like sleepwalkers, then our literary traditions are like wall clocks, there to make us feel at home. So:
1. To say that one of these wall clocks is right and another wrong is utter nonsense.
2. To say that one is five hours ahead of the other is also nonsense; by using the same logic you could just as easily say that it’s seven hours behind.
3. For much the same reason, it is 9:35 according to one clock and it just so happens that another clock also says its 9:35, anyone who claims that second clock is imitating the first is spouting nonsense.
A year before he attended Averroes's funeral in Cordoba, Ibn Arabi, who would write two hundrend mystical texts before his own demise, found himself in Morocco; it was during his sojourn that he penned a text inspired by the Al-Isra sura of the Koran. [...] Now, anyone who reads Ibn Arabi's account of his travels with his guide through the seven heavens and concludes, after noting that he was thirty-five years old at the time of writing, that Nizam, the girl of his dreams was right, and Beatrice wrong, or that Ibn Arabi was right and Dante wrong, or that the Book of the Israelites and Makan Al-Asra was correct while the Divine Comedy is incorrect, is perpetuating the first sort of nonsense I was describing.
In the eleventh century, the Andalusian philisopher Ibn Tufeyl wrote a book about a child abandoned on a desert island; during his sojourn there he came to respect nature, the sea, the life-giving sustenance afforded to him by a doe, the certainty of death, the heavens above and the "divine truths"; but claiming that Hayy Ibn Yakzan is six six hundred years ahead of Robinson Crusoe or that, observing the latter describes the tools and objects in greater detail, that Ibn Tufeyl was six hundred years behind Daniel Defoe is an example of the second kind of nonsense.

You can search Google Books to read Pamuk's interesting example for the third kind of fallacy.
"Gutenberg's True Innovation", not present in the article despite that being a paragraph heading, wasn't any of the things mentioned in the article.
Gutenberg created a system to easily cast letters as interchangable parts (centuries before Eli Whitney, as it were) This meant that Gutenberg built a system to mass produce printing presses
Carving the letters for an entire typeface by hand could take over a year. However, Gutenberg created a system for taking a hand-sculpted typeface, turning each letter into a mold, and then quickly and cheaply casting each letter. The result: mass production of the most difficult part of the system to produce, the typeface itself, and thus a way to mass produce printing presses.
This article is about as poorly researched as The Oatmeal's ode to Tesla.
i.e that white people invented absolutely everything and Europe is the only old world with history worth studying? Then again maybe it's changed in the past 15 years?
However, when I was in high school our textbooks were so concerned with political correctness that if anything they were overly focussed on diversity.
I took AP US history, World History, Asian History, and AP European History. The Average student only got one section of European history in the overall World History class.
>that white people invented absolutely everything and Europe is the only old world with history worth studying? Then again maybe it's changed in the past 15 years?
I find it very hard to believe (not impossible, just very unlikely) that you were actually taught that. More likely you just saw your history classes through your own biases.
E.g everybody knows when he studies history what this article says along the invention of the compass and gears and zero and algebra in Asia.
But people from western countries invented almost everything since the Guttemberg press, maybe because of this press, as books became hundreds or thousand of times cheaper that what they were before and Asian countries had to face an obsolete language with thousand of characters (Japanese realised they had such and inferior language and created higajana and katakana later).
Knowledge spread so fast other places could not compete. It has nothing to do with the color of your skin.
If China was not united during the incursions by European countries in the 1800's, maybe they'd have ended up even worse off.
With today's technology, would you say Chinese is now un-obsoleted?
We're taught as if there is a concrete separation between American History and World History, when in fact, teaching America separately means artificially separating it from the rest of the world and having to constantly compensate for that.
I find that very unlikely. If it is true please don't go around making statements like we are taught in america is that nothing happens outside of america.
You can't speak for America as a whole since we don't have a national curriculum.
More than likely you just feel the way you do because you just took US history and haven't gotten to any or the world history classes.
>We're taught as if there is a concrete separation between American History and World History,
There's nothing wrong with teaching a separate US history and world History class. When you get to college you'll find that history classes are even further subdivided by time and geography.
And college history courses assume that you already have enough knowledge from high school history courses to understand the historical context of what they teach, but by teaching American history separate (and before) world history, we are not taught any global context for events in American History.
If that's true you are an extremely rare case. I just took a look at the social studies standards for my state (Georgia, not exactly a top performer education wise) for middle schoool.
6th grade is the history and geography of Latin America, the Caribbean, Canada, Europe and Australia, 7th is Africa, Southwest Asia (Middle East), Southern and Eastern Asia, and 8th is US/Georgia History.
If you really haven't had any world history since 3rd grade it looks like it may have been a consequence of moving between 3 states.
If each state had world history at a different year in their curriculum, you may have missed them entirely.
Please don't try to speak for America on a forum with an international audience. Your experience is not representative.
When i was in elementary school in NYC, we learned about ancient civilizations and NYC history in 4th grade -- the ancient part was kicked off with a field trip to the Egyptian artifacts at the Met.
In high school in upstate ny, we studied global history and current events from grade 9 through 11. The Chinese portion sucked -- we basically covered the opium wars though the cultural revolution, but we studied many aspects of global history.
Well, Steve Jobs is a bad example here because he did create the first personal computer, as opposed to traditional mainframes, that was more than an experimental computer programmed using a switchboard and outputting with pulses of lamps. Maybe this is the point of the article, that Gutenberg's press was to the previous presses as PCs were to mainframes, but if it is then it's confusing.
Bill gates is a worse example because his company didn't make hardware until much later.

Expensive, but by no means did it take up a whole room.

Still not exactly a "personal computer". And still expensive, but getting closer.

The two Steve's were active members.
While there were mainframes that took up whole rooms, systems that didn't were available in the 60's, but at prices only large organizations could afford.
Early microcomputers were not the size of a room. The defining feature of a microcomputer was that it used a single microchip (integrated circuit) as its CPU, as opposed to needing one or more circuit boards full of components for that task.
