300 Years to Index the World's Information 248

Posted by Zonk from the everything-else-to-be-destroyed dept.
Kasracer writes "At the Association of National Advertisers annual conference, Google's CEO, Eric Schmidt suggested that it would take 300 years for them to index all of the world's information. From the article: 'We did a math exercise and the answer was 300 years,' Schmidt said in response to an audience question asking for a projection of how long the company's mission will take. 'The answer is it's going to be a very long time.'"

      I would assume that it would be to index the collective sum of information, even as it is growing. It's probably a lot quicker to index something than it is to generate it. With probable future advances in computing power and the development of new algorithms, it should be entirely possible that the speed of indexing (which already probably surpasses the speed of information production) would catch up to all the data that still hasn't been indexed.

      Think of it in terms of taking a ratio comparison of two infinite series.

Be interesting at least to find out what the order of magnitute would be - millions, or perhaps billions or trillions of man-years of unique recorded audio and video?

      I take it from that comment that you don't see much value in a thirteen year old girl's blog? What about a thirteen year old girls diary?

      Like Anne Frank's [wikipedia.org]?

      Fact is, it's incredibly hard to determine today what will have value tomorrow. Most of those thirteen year old girls (or 20-something geek guys) blogs will have no historical value. But some of those people will grow up to have a profound impact on the world (or they may not grow up, but still have a profound impact, as was the case with Anne Frank). It may be ten years from now. Or 50.

      Who knows what the writing they do now might tell us about what brought them wherever they end up? When people write diaries on paper chances are reasonable they'll survive and show up in an attic somewhere. But as more and more content get online, we also risk facing the loss of entire generations worth of many types of information to bit rot and simple lack of foresight.

        I think the parents question is perfectly valid. What is considered "information"? I'd consider a blog information, but is a painting some random artist creates included in this list of "information"? Is my laundry list information? How about my individual handwriting in my laundy list?

        The question of is something valuable isn't exactly an either-or proposition, but a matter of assigning a probability that a certain piece of information is valuable. Couldn't we agree that say the presidents day to day activities are more likely to be important in 100 years than say a single 13 year olds blog? Does that mean that 13 year olds blogs are worthless? Well no, but they aren't the thing I'd first choose to preserve.

        The question I have is, is the greater difficulty in control over online information balanced by the greater ease of keeping it around? Google doesn't delete messages from email for this very reason. We tend to throw stuff away because it takes up too much space, or because it just becomes clutter. But with increased storage space every year and better ability to keep track of it (and seperate it from things we consider important), why ever throw away information?

        Online information portability is obviously a problem. How do you move someones blog somewhere else, and have it mean anything in say 50 years? I think these problems will be solved as people expect information to be more portable and standardized. The solutions I think will come from the short term portability and needs rather than a few people wanting to preserve something for the next 100 years though. Many people make the assumption that standards are short lived things that are here today, gone tommorow. I'd have to disagree on a historical basis. How old are reel to reel tapes, and you can still find a player at say a thrift store. CD-audio has been around for 25 years and is still the default medium for music today. Ascii has developed I don't know how long ago and yet still is quite popular and if you have a computer that can't read it, you've got a fairly useless computer. Standards have a way of sno-balling and gathering momentum to live on a long time.

        Interpolation means looking between your data points, and extrapolation means looking outside the data set. Interpolation is generally much more reliable and trivial than extrapolation.

    I think it is important to remember that this was a math exercise not a serious study with predictive power. I remember several years ago people thought the human genome project was insane. They thought it would take hundreds of years to catalog our entire genome and cost some ludicrous numbers of trillions of dollars.

    Then:

    In 1999, the goal of producing a "working draft" seemed very far away, with less than 15 percent of the genome sequenced. If the accelerated goals had not already generated a sense of urgency in the consortium, a decision by the sequencing center leaders at a February meeting in Houston would. At the meeting, the leaders accepted Dr. Collins' challenge to ramp up their efforts to produce a "working draft" by spring of 2000. By January 2000, the centers were collectively producing 1,000 base pairs a second, 24 hours a day, seven days a week, and 2 billion of the human genome's 3 billion base pairs were sequenced by March. At a White House ceremony hosted by President Bill Clinton in June 2000, Dr. Collins and J. Craig Venter of Celera Genomics, which had carried out its own sequencing strategy, announced that the majority of the human genome had been sequenced. [from here [nih.gov]

    I tried to find the graph of speed over time because I have seen itseveral times. It shows the exponential increase in the speed of the project. Apparently there are many scientists that believe with techniques as they are now we could repeat the project in 2 years if we started over. The indexing of information could have a very similar timeline. Very slowly at first and then as technology and specific methodology develop off you go. So the truth is... this is a guess. I wouldn't put too much faith in it.

    "Of the approximately 5 million terabytes of information out in the world, only about 170 terabytes have been indexed, he (Schmidt) said earlier during his speech."

    So ... how many terrabytes of info will be produced in the next 300 years, and does anyone really think that Google (and anyone, or everyone) could keep up?

    Especially, once all 20 billion people who live in the Solar System are video-documenting every moment of their existence ...

You could consider the approximate location of every molecule in the universe a piece of information. Perhaps just text could be considered - that would narrow down the field of information into the finite. But Google does mapping, so they already have broken out of just text. Then you have the fact that the amount of inform
