Happy birthday internet Europe!
Twenty five years ago last November, internet first started flowing into, and out of, the Netherlands and Europe.
Here in Amsterdam at the CWI, in an office next to mine.
I was probably the 4th or 5th user of the internet. Maybe the 6th.
It was a "Skunk works" project.
There was a 64kb/s connection between the whole of Europe and the whole of the USA... a year later to much rejoicing it was increased to 128Kb/s
Moore's Law
You have probably heard of Moore's Law.
It's not actually a law.
In 1965 Gordon Moore predicted that integrated circuits would double in power each year at constant price 'for at least 10 years'.
In 1975 he adjusted that to a doubling every 18 months.
Functions
When you turn a tap on, you are adding a certain amount of water per minute to the bath.
A tap filling a bath
Linear graph
So if we look at the graph of the bath filling, we get something like this:
We call this a linear function.
Bank Savings
However, for instance, when a bank gives you interest on a bank account, it is not adding a fixed amount every year, but an amount based on how much you have in the bank.
For instance, if they offer a 3% interest, then every year your money gets multiplied by 1.03. If you have €1000 in your account, then at the end of the year you will have €1000 × 1.03, which is €1030, €30 more. At the end of the second, you will have €1030 × 1.03, which is €1060.90, €30.90 more, and each year the amount added is more than the year before.
Moore's Law is also a multiplication: a doubling every 18 months (which is 59% annual interest, if you are interested, or about 4% per month).
Exponential
If we draw a graph of Moore's Law since 1988, it looks something like this:
Moore's Law graphically
In other words, a computer now is around 130 000 times more powerful than in 1988.
We call this an exponential function.
The Knee
If you look at this graph, it looks like almost nothing is happening until 2005, and then suddenly it shoots up like a rocket.
Some people, when talking about exponential functions like this talk about it "having passed the knee", meaning, it has finally taken off.
But I have some bad news.
There is no knee
If I draw the same graph, but only up to 2006, suddenly the knee appears to start around 1999.
There is no knee: it is an artifact of the scale you use.
Moore's Law up to 2006
Logarithmic scales
And that is why it is better to graph exponential functions in a different way.
On the vertical axis, rather than going in steps of 1, 2, 3, ... we use steps of 1, 10, 100, 1000, ... Then the exponential graph looks like this:
If you use a logarithmic scale, and the graph looks like a line, then it is exponential.
Actual data
Of course, computers don't get exactly twice as powerful in exactly 18 months.
But I have been collecting data on the power of my computers since 1988.
Laptops 1988 - 2013
Moore's Law
OK, so we all know Moore's Law now.
But often people don't understand its true effects.
A BBC reporter once said: "Your current PC is more powerful than the computer they had on board the first flight to the moon".
Right, but oh so wrong (Closer to the truth: your current computer is several times more powerful than all the computers they used to land a man on the moon put together.) Let me explain.
Take a piece of paper, divide it in two, and write this year's date in one half:
Paper
2014
Now divide the other half in two vertically, and write the date 18 months ago in one half:
Paper
2014
2012
This represents a comparison of the power of a computer bought now with one bought 18 months ago.
Now divide the remaining space in half, and write the date 18 months earlier (or in other words 3 years ago) in one half.
Paper
2014
2012
2011
Repeat until your pen is thicker than the space you have to divide in two:
Paper
2014
2012
2011
2009
2008
2006
2005
2003

This demonstrates that your current computer is more powerful than all other computers you have had put together.
(You can use this diagram to demonstrate other things too).
The need for speed
Amazingly, networks get faster even faster than Moore's law! They double in speed (at constant cost) every year!
As I said, the first internet connection in the Netherlands was a 64kb/s connection. A year later it was doubled to 128Kb/s.
But that is exactly the increase we should have expected!
Well, if that is true, the speed at Amsterdam now should be 64kb/s × 225 which is 2Tb/s.
So let's have a look at AMSIX's statistics from recently:
AMSIX last week
AMSIX daily stats
Yep! A little over 2Tb/s!
So since 1988, computers have got 130 000 times faster, but the internet 33 554 432 times faster...
Exponential Bandwidth Increase
This is my home bandwidth over 30 years.
Exponential change
This is November 2006:
Six years later, the cheapest 4GB stick cost €2.99.
Screens are subject to similar drops too.
Will Moore's Law come to an end?
Surely, but don't hold your breath. Over the years, I have heard many predictions that it was "nearly" at an end.
Processor clock speeds have reached their maximum.
The increase is now in number of cores. (Although a CPU now has a handful of cores, GPUs -- which contain maybe 90% of the power of a computer -- have around 1000).
We will have to find a new computing paradigm to deal with the ever-increasing number of cores.
The Future, the Past
If you want to think about the future, you should think about the past too.

Might this be true? Thanks to the Semantic Web and europeana.eu I could answer that question:

Abbey Gateway, St. Albans
The third printing press in England was set up here in 1479
1485 Chronicles of England
Printed on that press. Note how it imitates a manuscript.
The Book
Until the introduction of printing, books were rare, and very, very expensive, maybe something like the same price as a small farm.
Only very rich people, and rich institutions, owned books.
The first Universities were set up before printing, and if you were a student, the price for borrowing a book was copying it. Usually book lenders only lent you part of the book at a time, to speed up the copying.
The other producers of books were the monasteries.
Monasteries
"When the Anglo-Saxon Monkwearmouth-Jarrow Abbey planned to create three copies of the bible in 692—of which one survives—the first step necessary was to plan to breed the cattle to supply the 1,600 calves to give the skin for the vellum required."

Comments
Producing books was slow, expensive, time-consuming, and tedious, as evinced by some of the remarks written by monks that have survived in the margins of manuscripts:
Oh, my hand.
Thank God it will soon be dark.
Writing is excessive drudgery. It crooks your back, it dims your sight, it twists your stomach, and your sides.
St Patrick of Armagh, deliver me from writing.
As the harbour is welcome to the sailor, so is the last line to the scribe.
Now I've written the whole thing: for Christ's sake give me a drink.

1500
By 1500 there were 1000 printing shops in Europe, which had produced 35,000 titles and 20 million copies.
Price of books greatly diminished (First bible 300 florins, about 3 years wages for a clerk).
Books became a new means of distribution of information.
It was a paradigm shift - new industries, bookshops, newspapers.
Many ascribe the enlightenment to the availability of books.
Information increase
1665: first scientific journals French Journal des Sçavans and the British Philosophical Transactions
From then on the number of scientific journals doubled every 15 years, right into the 20th century.
Even as late as the 1970's if you had said "there has to come a new way of distributing information to support this growth", they would have thought you crazy, more likely expecting the growth to end.
But now that we have the internet, the amount of information produced continues to increase at an exponential rate (doubling every three years according to one report, every 11 hours according to a newer one).
Information growth

The price of technology
We actually use Moore's law to reduce the price we pay, at the same time as increasing the power (in 1990 people were willing to pay ¤4500 for a desktop computer).
(¤ is the international character for "unit of currency", and it doesn't matter here whether we use $ € or £, since we are talking orders of magnitude)
We have seen
- ¤1,000,000 mainframes in the 50s
- ¤100,000 minis in the 60s
- ¤10,000 workstations in the 70's
- ¤1,000 PCs in the 80's
We really should have expected the emergence of the ¤100 machine, and the question is really why it took so long.
The ¤100 Computer

Usage of the ¤100 computer
Carry round, plug into larger screens and keyboards. Tablets.
No longer one computer per family: need to store data off the computer.
Bandwidth is doubling per year, documents 'in the cloud'.
¤10 computer
Still working out how we are going to use it.
¤1 Computer?
Certainly we should get close to that in the next decade.
The main problem is packaging costs: it is noticable that once a class of USB memory sticks (for instance 1GB) get to €3, they stop making them, because the next higher class starts reaching that price, and they can't manufacture (and ship) them for less than that.
Still, €3 is ¤1 according to my definition, so we should just reach that point.
1968: The Internet is born
The internet was a cooperative effort.
As I said, in 1988 it arrived in Europe: speed 64kbps connection for the whole of Europe to the whole of America. A year later that doubled to 128kb, and has doubled every year ever since.
The true cost of communication
In 1988, phoning long-distance was expensive, and the further you phoned, the more expensive it was. People considered it reasonable, because it matched their expectations.
In fact, the expensive part is the local loop: only one person (you) is using that. The long-distance part can be amortised over 1000's of calls.
The internet made this all to clear: going to a site in New York is no more expensive than going to one locally (and now, phoning Amsterdam-New York is even cheaper than phoning Amsterdam-Amsterdam!)
1990 The Web
Tim Berners-Lee, and Englishman, and Robert Caillau, a Dutch-speaking Belgian, created the Web at CERN, on the border between Switzerland and France.
Just like Gutenberg with the printing press, they brought together many existing technologies (Hypertext, the internet, MIME types) and created a cohesive whole.
And frankly, the Web is replacing the Book (along with many other things).
Telephone directories, encyclopaedias, train timetables, other reference works are already gone. Most others will follow. Books (as an artefact) are about to become a niche market. All information will be web-based.
That is why it is of utmost importance that we plan properly.
Usage of new technologies
Typically people expect that we will use new technologies in the same way we use existing ones.
Steam engines in factories: there was one engine, with lots of pulleys to distribute the power over the factory.
It was assumed that the same would happen with electric engines: one engine in the house with pulleys taking the power to where you needed it.
In houses they thought there would be vacuum cleaner tube attachment points in every room, with one central motor in the basement doing the sucking...
Same with mainframe computers: it was assumed 5 would be enough. Why would people want personal computers? They don't need to do payrolls!
The new imitates the old
The first books looked like manuscripts.
The first cars looked like carriages.
First radio was like plays, actors still had to dress up.
And the Web is (still) imitating old media.
Future Web
The current web is still very immature:
Content is presentation-oriented.
Little device independence
Little accessibility
Little machine-readability
Authoring is too hard - needs programming skills.
What is to come
Interlinking of services
Data doesn't need to be human-readable; in fact it must be machine-readable.
If there is data, make it available! (Amsterdam fireservice has trouble finding out where there are roadworks).
Internet everywhere, lights, oven, your alarm clock: internet over the electric net, so that anything that plugs in can have a connection.
All communication via IP.
Everyone a publisher
Nothing unavailable
True costs - like the internet showed with long distance calls, so we will learn the true cost of content.
A second enlightenment?
A lot of existing information is distributed by people who have concentrations of the means of distribution, and in fact that is the real reason they exist.
- Newspapers
- Books
- Scientific publications
- Music
Music industry is healthy, record industry is not.
Old media struggling to retain ownership (compare region codes on DVDs)
A change in the means of distribution.
A change in the availability of information.
The end of the hit.
A paradigm shift
Paradigm shifts
My grandparents: when they were born the only 'modern' technologies they knew were trains and photography.
No hot water, no gas or electricity, no flushing toilets.
And think of the changes that they saw in their lifetimes: cars, electricity, radio, movies, talkies, TV, computers, credit cards, cash machines, ...
In fact it seems that paradigm shifts are happening more and more frequently, and have been for a very long time
The Singularity
(From wikipedia)
Conclusions
Make no mistake: we are at a turning point in history. The internet is going to have as great an effect on society as the book did, only much quicker.
Newspapers, music industry, books in trouble? Pah! Nothing. Just wait!
The means of distribution are changing hands.
"The classified ads (and stock market quotations) are the bedrock of the press. Should an alternative form of easy access to such diverse daily information be found, the press will fold." Marshall McLuhan, "Understanding Media", 1964
"We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run." Roy Amara, The Institute for the Future
