Have you heard of the genetics division of Google, while it may be rather small it does exist according to several sources. Google seems to want to really get into each and every one of us. They want to know what makes us tick, and they must think that genetics has something to do with that. Imagine a day in the future when genetics will screen what kind of ads you view.
However, this brings up the issue of privacy vs. knowledge. Knowledge is power and will always help us decipher complicated things in the world, but people like to be left to themselves sometime and value their privacy highly. As a huge company I think Google should be able to draw the line of what is right and wrong…at least I hope!
