text: First, I would like to say that this is a really good topic the author brings forth to the table, but who would want to feel like their being watched? "For example, if you smile when a Web ad appears on your screen, a similar ad might follow. But if you frown, the next ad will be different." This information is truly invalid. Smiling at an ad does not make it appear the next time you get on a different website, and frowning at an ad doesn't change it either. It's the way the ads are set up that it makes them leave or come back. Student's shouldn't have to feel like they have to fake their emotions just so that the computer doesn't recognize how they feel in reality. I do not believe in this "new technology" that seems to be changing the way we see ourselves. I would not want kids to feel like they are being watched or even judged on by what they look like through a computer screen.
