I know a lot of people already know about this, but I thought it was an interesting topic to put up for discussion.
Even if you did know that machines watch you surf the web, by the time you found out it was already too late. The technique called machine learning “affects the kind of Internet advertising you see on Amazon.com, but most people don’t realize that is the underlying technology” (livescience). The ads we see online are often put up by machine learning systems to “learn” how people use the Internet. By comparing your activity with other users, the “agent” targets what ads you are most likely to respond to. Then, every time you click on an add, the host site (usually Google or Facebook) charges the advertiser.
So how do machines learn? They start out at the level of a child and have to learn more to progress further in “intelligence.” For example, the article mentions that “like school children learning arithmetic from a teacher, some agents can use simple examples and feedback to learn how to approach more complicated information.” Other agents rely on experience: using the responses from their past “decisions” to deal with similar situations. What is most important to notice is that these machines figure out the patterns in the data they receive. The downside to teaching a machine to learn is that they are doing so based on a model of human learning. This causes some issues because we don’t fully know how the human brain works. So for now, these machine learning programs can only process a limited amount of information.
So, what does this mean for us? It probably means that advertisers are going to get better and better at reading the individual’s wants, so that everyone is constantly being barraged online by things they really want. It took decades for advertisers to hone their methods to personalize ads, but machines are already able to do it faster and more efficiently. When the technology is perfected, consumers’ only option will be to “just say no.” Watching a commercial for something is awful, boring, and frustrating. Ads placed on websites are hardly notices because you’re focusing on whatever else you’re doing. If you do click on those, you certainly don’t feel like you’re saying “yes” to purchasing something, but you totally are.
I’m sure other (and much creepier) implications can be drawn from this too. It presents a great “Big Brother” opportunity for everyone from the ad agencies to the government being able to monitor what has become a pretty crucial part of our consumer culture: what we want. Professionals can build complete personality profiles based on what ads you respond to, and who knows who they would be willing to sell those to? Anyone?
