Kamel pointed out to me this AAAI Symposium on Social Information Processing. The name of the event is cool. It will be held at Stanford.

Social media facilitate new ways of interacting with information - what we call social information processing. Social information processing allows users to collaborate implicitly by leveraging the opinions and knowledge generated by others. In addition to collaborative problem solving, social information processing may lead to wholly new kinds of knowledge, that emerge from the distributed activities of many users.

Ever since I setup a web page, even before I even knew what a blog was, I have had the following odd experiences. People get in touch with me, in some way, typically by email (but not always), because they do not know how to do something and want me to help them. I am not talking about a business seeking my help, but rather just a random individual, sometimes a software developer, sometimes an engineer, sometimes a student… seeking free help. Students are especially likely to seek free help.

When it concerns my published research, this is usually very pleasing to me: I love to answer questions about my research.

However, quite often, the questions are just “work”. By that I mean that they are exactly the type of questions that you pay a consultant to answer. Being a pseudo-polite person, I most often answer the question quickly, sometimes giving a pointer, most often just saying I cannot help.

At some point in time, when I was very active as a consultant, prior to rejoining the research world, I would sometimes agree to answer, for a fee. Only once did such an individual agree to pay: I then produced a sample Java code… it took me about an hour to test, document, and ship the result. The fellow wanted to compress some images in a certain way. I charged him US$150. He complained that I charged too much and never paid.

I am aware that doctors, lawyers and accountants sometimes answer questions without charging people. But the type of questions I get often require 15 minutes or more of work. My expertise has been acquired over the years through hard work. In fact, I estimate that I have invested far more in growing my expertise than most doctors, lawyers and accountants.

Today, I got two questions in my inbox. One of them was “I downloaded this script from your web site, and it does not work for me, can you tell me why.” This fellow expects me to invest 15 minutes, 30 minutes or more. Meanwhile, he will attempt to turn around and charge other folks for the result, either because he is an employee or a consultant himself. Do you think he will be willing to pay my fee? Then, a graduate student from emailed me a question about some algorithm I once used in a paper. This algorithm is generic. Explaining the algorithm to the fellow in question would require about half and hour. Do you think he is willing to pay my fee?

This annoys me profoundly because it suggests that in some people’s mind, science and technology skills are not valuable. Somehow, my time is less valuable than an accountant’s time. I am annoyed that people consider medical, legal, or accounting advice to be worth paying for, but science and technology advice should be free.

I am not saying serious businesses hold this view. But the public does.

(Of course, several businesses do seek free services. Anyone who has been a consultant knows this. There is a category of clients you always get: they want stuff for free on the implicit promise that they will make it up to you later.)

To be fair, the public also does not feel like paying for financial advice: if you call up a financial expert, he will probably charge you nothing, but get a commission on whatever he can sell to you.

I do not know where this whole advice-should-be-free attitude comes from. I much prefer paying for advice. I want my financial advisor to get paid by me, not by the fund managers.

An even deeper issue is that when the public consider that science and technology skills are free, I think you eventually end up with very good doctors, lawyers, and accountants, but you outsource engineering and science to other countries. You also end up getting poor advice about where to invest your money because you are not willing to pay (directly) your financial advisor.

Paul Graham, the millionaire, Harvard graduate, Italy art school graduate, the same guy who wrote that Americans would keep the upper hand because all of the best professors are parked in a few small elite colleges instead of wasting their time all over the country teaching to lesser kids, the guy who has written that elite colleges were important because that is where the most brilliant kids meet up and create the best start-ups, the guy who wrote that keeping housing extremely expensive and refusing to tax the rich was key to producing innovation, well, this guy had revelation last week:

It may not matter all that much where you go to college.

Wow!

And he had this revelation because, time and time again, when recruiting kids for his start-up incubator, he found out that kids who graduated from MIT, Stanford or Harvard were not smarter.

How he explains it is great too:

Because how much you learn in college depends a lot more on you than the college. A determined party animal can get through the best school without learning anything. And someone with a real thirst for knowledge will be able to find a few smart people to learn from at a school that isn’t prestigious at all. At most colleges you can find at least a handful of other smart students, and most people have only a handful of close friends in college anyway. The odds of finding smart professors are even better. The curve for faculty is a lot flatter than for students, especially in math and the hard sciences; you have to go pretty far down the list of colleges before you stop finding smart professors in the math department.

(Also see my post Big schools are no longer giving researchers an edge?)

Thomas has evidently been reading David Weinberger. He points out that

The Web folds space in a way that (most of) human knowledge is within our arm’s reach.

He then asks how Frank Herbert would have felt.

Myself, I always ask myself, whenever I read a pre-Web SciFi novel, whether the author could have foreseen the Web.

In any case, it is true that the Web warps time and space. By that I mean that where, physically, the documents are is without concern for you. The Web also speeds up information retrieval tremendously.

Suppose you were the only human being with access to the Web as we know it. You would be able to pull out knowledge faster than any other human being. You would appear like a super hero. You can tell instantly the prices of a given product in hundreds of stores. You can get a satellite view of any house in your area, in seconds. And so on.
