useless

There are many inventions that have been made to aid humanity. Vehicles have made transportation much easier, and computers and telephones have revolutionized communication. Hundreds of little gadgets have made small inconveniences an afterthought, for example, my roommate has this small desk lamp that is touch sensitive, eliminating the need to reach up and twist a knob. Electric toothbrushes make brushing arguable more fun. These types of gadgets make everything a little more convenient, and more efficient.

so why do some inventions backfire? Idealisticly they are supposed to make things better. self-checkouts at grocery stores are a great example. They were designed to cut checkout times and get more people out of the store. When have they ever worked properly? Every time I try to use one the machine blares in a loud female voice," PLACE THE ITEM IN THE BAG!" then something starts to beep and the teenager at the command center looks at you like you don't know what you are doing. Items don't scan, and people behind you are getting restless. By the time everything is finished you could have been through the line with the cashier. They never work the same way twice. Sometimes it is better to just stick with what works, rather than screw things up with a new invention.

There isn't enough crap anyway.
