An article on Read/WriteWeb says that Google Maps are now editable by anyone with a google login (which surely must be everyone by now). The idea is that you can change the address, location, and link for any of the designated places on the map. This is a very cool step forward in crowdsourcing. It will be interesting to see how well they control vandalism.

One of the interesting questions is what methods Google is using for watching for vandalism.Many crowdsourcing sites seem to be using a “security through obscurity” approach. I wonder if it will prove over time that open approaches that publish effective security methods work as well? The ESP Game seems like one good example: the rules are published, but by working to ensure the players are strangers, most attempts to hack the system are not effective.  (The slashdot attack is a good counter-example.)

What do you think? Excited? Worried?

There’s a fun article in the Winter 2007 AI Magazine about “Machine Ethics“. The basic argument is that as machines get more and more in control (e.g., planned army robots that would fire weapons), it is more and more important (to humans) that they behave in an ethical manner.

The article argues that there is a fundamental difference between implicit and explicit ethics. Implicit ethics would be programmed into a machine by its designer, much as Asimov’s imagined three laws of robotics. Explicit ethics would also be programmed in by a designer, but at a more fundamental level: the robot would be able to compute the ethics of new situations based on a fundamental understanding of ethics. The authors argue that explicit ethics are necessary for several reasons:

1) So it could explain why a particular action is right or wrong by appealing to an ethical principle.
2) Because otherwise it would be lacking something essential to being accepted as an ethical agent. (Kant admired agents that work consciously from ethical principles more than those that work slavishly from rules.)
3) So it could adjust to new situations, evolving the appropriate ethics.

(1) is a red herring: explanation systems often appeal to principles they don’t understand in any sort of principled way. For instance, in our work on explanations for recommender systems some of the most effective (for humans) explanations were only loosely connected to the operation of the recommender.

(2) is in contradiction with an argument the authors make later in the paper. They argue that even though computers won’t be conscious in the near term, they should be accepted as ethical agents if they act ethically. Agreed! So, then, all we need is that they act ethically.

(3) is intriguing. On the one hand, it would be remarkable if an AI agent could evolve new ethical patterns for situations it has never seen, based on core ethical principles.On the other hand, the results of that evolution might be very surprising. For instance, if a military robot were to decide, based on ethical principles, that it ought to prevent an attack on Iran that a general wishes to carry out, how would that be perceived, by the military, by the loyal opposition, by the anti-war effort? What if the robot assassinates the general to prevent the war? Overall, given our track record in predicting the performance of complicated software systems, I have some doubts about this approach.

I liked a later quote in the article, which says that ethical relativists cannot say that anything is absolutely good, even tolerance.

I just set up an account for my daughter with audible.com, and downloaded a book for her to listen to on the bus. The good news is that is appears to be all set up now, and ready to download to her iTouch. The bad news is … everything else.

We spent nearly an hour buying a single audio “book”, and getting it copied down to her computer. The problems were nearly all related to digital rights management, though I’d class them in two groups: fundamental, and incompetent.

The fundamental problem is that DRM makes downloading and using media much more difficult. It restricts which programs and devices you can use it with. Further, is it any surprise that downloading a program whose fundamental purpose is to prevent proscribed uses of a media file makes it more difficult to successfully use that media file? In the case of audible, we had to download a program to my daughter’s laptop that insinuated itself into firefox and itunes in unspecified ways, so that she could download the Audible files she had paid for to her laptop, and thence to her iPod. This program failed to install itself properly the first time — apparently it doesn’t check to see whether itunes is running, but fails mysteriously if it is. When we tried to download the book we had paid for to her computer, we kept getting mysterious error messages. These went away once we reinstalled the software.

The problems of incompetence were mostly caused by a user interface that tries to pretend that the challenge is easier than it actually is. The Web site makes a big thing out of the four simple steps required to get going with Audible. Step 1 is “Pick a plan”. We didn’t want to sign up for a plan, so it took us a while to figure out that you can buy books without a plan. Step 2 is “Download Audible software”. In the description it says “You can also use ITunes to download audio …”. We decided to go that route initially, before figuring out that apparently the audible.com software is required in addition to iTunes. It didn’t help that the iPod Touch is not listed in the “supported devices” list, so we had to guess which software we need. Step 3 is “Purchase and download”. Our problems with this step are described in the previous paragraph. Step 4 is “Transfer your audio to your AudibleReady device”. Here the solution was easy: we just had to figure out that Audible had created a new sort of “playlist” in iTunes, and that we had to tell iTunes to sync that playlist with the iPod Touch. A common step in iTunes — but it would have been nice for Audible to walk us through that step.

A very frustrating hour later, my daughter is pretty happy with having her book ready for the bus. I’m much less happy. Audible seems like a company that is going to fail if they don’t figure out these user interface issues. What, then, will happen to the DRM that requires a “phone home” to install the book on a different device? (Yes, even the iPod Touch will one day seem outdated.) Even though I’m eager to listen to “books on pod” while I exercise, I refuse to buy these DRM-crippled alternatives. Yes, convenience is worth a lot, but more important to me is the principle that media that I buy must be usable for me into the murky future, independent of the survival of any one company, format, device, or business model.

Newsweek has an article that argues that Web 3.0 is going to be all about injecting the experts back into the information production and dissemination process. I think they’ve gotten the big picture badly wrong, but the saddest quote in the article is about why one of the ‘experts’ they interview thinks this change will come about:

Fueling all this podium worship is the potential for premium audiences—and advertising revenue. “The more trusted an environment, the more you can charge for it,” says Mahalo founder Jason Calacanis, a former AOL executive who was previously involved with several Web start-ups. It’s also easier to woo advertisers with the promise of controlled content than with hit-and-miss blog blather. “Nobody wants to advertise next to crap,” says Andrew Keen, author of “The Cult of the Amateur,” a jeremiad against the ills of the unregulated Web.

Pretty amazing that the argument is that advertisers are going to fight to prevent the amateurs from taking over information processes so they can protect their advertising revenue. (Newsweek is, of course, heavily supported by advertising.)

It’s also interesting that none of the examples they give in the article — from Google’s wikipedia killer to the Maholo search engine — have any real traction in the marketplace. I think we’re seeing a fantasy here. People whose business depends on the elites managing who reads what where and when are arguing that we have to return to that model to make sure “good” information gets out.

I was speculating the other day about how different the world would be if there had been some way that radio and television could have been supported through a fee-based model, rather than the advertising-based model that we have today …

Read/WriteWeb has a look at a very interesting new Web site called Traackr.  The idea is that you tell Traackr all of your media accounts (YouTube, Flickr, MySpace, etc.), and Traackr logs in every day to see if you have new content, and to see who has been looking at your content.  Traackr then generates cool graphics showing how much visibility your different content items are getting across the entire Web.  After all, what could be more interesting than seeing how interesting you are!

The idea of a site that brings together all of your accounts around the web is not new, of course, but it could be very valuable.  Traackr is less interesting than some efforts in that it is focussed on showing you what is happening on all of those sites, rather than on helping you remember all your usernames, passwords, and how you actually interact with each of them … but it’s at least a step towards bringing together information about these accounts.
