Exponentials R Us: Seven Computer Science Game-Changers from the 2000′s, and Seven More to Come

3. Smart bodies. When you take your car into the shop, the mechanic plugs in a diagnostic computer that analyzes a log of performance data and immediately pinpoints the sources of problems—problems you are aware of, and problems you are not. When you visit your doctor, she says “Where does it hurt?” Why is your body not as well instrumented as your car? It will be. The jock market will drive this, but it will become ubiquitous.

4. Smart robots. In the 20th century the U.S. led the world in four great waves of technological advancement: electrification, automobiles, airplanes, and computers. The first large technological wave of the 21st century is shaping up to be robotics. Robots are migrating from structured environments (assembly lines) to unstructured environments (homes, offices, battlefields). The potentials are limitless.

5. The data deluge. The rapid emergence of inexpensive high-bandwidth sensors is transforming every field from data-poor to data-rich. The challenge is to develop automated tools – based on approaches such as data mining and machine learning – to extract knowledge from this mass of data. Whether you are a scientist, an eCommerce site, or a sports team, your future competitiveness depends upon this capability. “eScience” is the buzzword.

6. Virtual and augmented reality. It’s been just so much yap for the past decade, but it’s going to become real in the next. For example, think about Google Street View or Microsoft Photosynth, but with all the world’s photographs from a few billion smartphones. New breakthroughs in computer vision are making this possible.

7. Smart crowds and human-computer systems. Computers are great at multiplying large numbers. Humans are great at recognizing images. What if you need to do both? UW biochemist David Baker, working with UW computer scientist Zoran Popovic, has augmented his Rosetta protein structure calculation software with a web-based videogame providing human guidance. (Teenage gamers are beating the pants off of Ph.D. biochemists – there’s such a thing as too much education.) See it here. More generally, crowd-sourcing, a development of the past decade, will explode, enabling the rapid construction of small, innovative companies.

Note that these are not “just applications” (although there is nothing un-cool about “just applications”). They require fundamental advances in computer science.

Thanks to Tom Anderson, Jean-Loup Baer, Rodney Brooks, Jon Froehlich, Pat Hanrahan, Peter Lee, Hank Levy, Pat Lincoln, Shwetak Patel, Steve Seitz, Sebastian Thrun, and Dan Weld for sharing their ideas with me.

    Listening to Ed off-and-on for over 30 years, I am always impressed with his insight and ability to synthesize and summarize deep thoughts. Great post!

    “Teenage gamers are beating the pants off of Ph.D. biochemists – there’s such a thing as too much education.”

    WOW! Is there data to support this? Please share! This could have very important implications on our strategies for promoting science education!

    : A decade ago, your mobile phone was a brick, and all you could do with it was make calls (if you were lucky!).

    A decade ago, my mobile could (and routinely did) purchase coke from vending machines, pay for parking tickets and text to anywhere on Earth. I wasn’t in the United States though, which is the point of my comment. The list is very US-centric. I’m sure our Japanese mates are laughing at your list as well.

    The data deluge is unlikely to be driven by high bandwidth sensors, rather by many billions of low bandwidth sensors that, in the aggregate, requires lots of bandwidth. Most sensor transactions are and will continue to be but a few bytes of data each.

    Where would have you gotten the fast computers and high bandwidth connectivity if electrical engineers and communication engineers would not have worked their asses off. The list has been made from just one point of view. Its as shame that you are unable to see the bigger picture. No discipline is small or big. Its the mix of everything that creates the impact. Alas you are too rude to understand this.

    “Teenage gamers are beating the pants off of Ph.D. biochemists – there’s such a thing as too much education.”

    Pure hyperbole. Or gross simplification. In the example cited, the team that created the environment where video gamer apply their visual analysis and orientation skills to protein structure analysis was lead by two two PhDs. It is false to draw the conclusion there is “such a thing as too much education” based on this example. It is more accurate to say that deep knowledge, education and creativity enabled Dr. Baker to have the insight that it may be possible to harness the abilities of population of people with a set of skills different from that of the usual protein research scientist. And enabled Dr Popović to translate the all the complexities of modeling protein structures into a scientifically accurate – and fun – “game” that enabled those gamers to contribute meaningfully, in a manner not possible by the brute application of rules and computation power. WIthout the PhDs setting the stage, these teenage gamers would likely be contributing nothing of value to the advancement of science.

    That being said, it is a very very cool tool, more so if it actually influences some young teens to pursue the study of science.

    Rangeen: The list is fucking called Seven COMPUTER-SCIENCE game changers….

    It’s about CS. Go make your own list.

  • ChrisFizik

    with computer science in the title here I thought this list was going to be way more technical or concept/theory based. I get the impact / influencer / Exponentials R Us idea…..but this could have been a bit more specific rather than a ‘Technological advances of the decade’ list….

    Great Post!

    I’m currently working on a project designed to make high school students more aware of the roles that IT in general and CS in particular play as societal agents of change. Lists like this help highlight those changes and make my job a little easier.
