Rate the following essay on its writing, argument, and language skills:
The computer software to read a humans' faces can be helpful, but it can also be harmful. It can be helpful to know what kind of lesson plan that your students are interested in and what ads to put up on their computer. It can be harmful, because what if the student does not want to talk about their emotions and they are having a rough day. Not everyone would want to have the feelings known by everyone.

The computer could use your emotion to manipulate you, and make you do things you woundn't normally do. Like bring up ads to make you spend money that you don't nesessarily have. Or bring up ads that make you go on a website that you really aren't supposed to be on. All of these things can cause trouble and the emotion reading software may seem like not such a brilliant idea.

The software may malfunction sometimes and read your emotion wrong. Giving you things on the computer that you do not want to see. You can become irritatible with your computer knowing that it knows how you're feeling all the time. It can become scary, and it may feel like someone is watching you just because your computer knows your emotions.

Not everyone would want this software on their computer, so it may not be as profitable as it was initially intended to be. When you are in a bad mood you don't want little things bothering you. Which means you don't want ads popping up evrywhere; even though you are interested in those ads you may not want them popping up too frequently. The software maybe inaccurate sometimes and that may cause problems. Evidently, this is not a good idea.
