Rate the following essay on its writing, argument, and language skills:
Is technology that reads emotion expressions really that valuable? It helps you tell someones emotion and that could help the world find out more about paintings or people in general. People hide emotions and that is not okay, people need to know when their friends are mad, sad, depressed, happy, angry, etc. It helps those people know if they can for example, say a joke or not, talk about certain things, tell a story. What if we could spend our time and money into something else that is more important. This is a really cool peace of technology but is it really worth it.

Is this emotion expression reader really worth it in the grand scheme of things. It is very cool to find out how people are feeling in pictures or how your friends are feeling but do we actually need it. People could be spending money in other places. It is nice to know how people are feeling because someone could tell if they are just pretending or really smiling. This could also helps people find out if somone is depressed or not. If a kid is depressed and angry about something we could use this to find out if they are faking a smile or if they have been cured from their depression. The emotion expression reader has some value but is it really that great.

This machine that reads emotions can be valuable if used in the right ways. We can scan someones face to see if they are depressed or if they are cured and are actually happy, Yet there are other places we could spending money, we could spend it on technology that matters more, like vehicle technology, computer technology, improved cell phones. People can be careless with there money and spend it on all the wrong things. It is cool to find out how someone is feeling just by one simple scan, we can know if someone is sad, happy, angry, surprised, disgusted, or fearful. This piece of technology can be useful in some ways.
