Coffee filters. Dishwashers. Hair brushes. Windshield wipers. Computer programming language. Try to imagine how your day would go without these things.
Unless you live in a cabin in the woods and couldn't care less about modern conveniences (in which case, you're probably not reading this), the answer is "not well."
Think about it: Getting ready for work probably took people 10 times as long without paper filters to make coffee, hair brushes to tame bed-head, or windshield wipers for safe driving in storms. Then, of course, once you finally got to there, you'd be doing all your research, correspondence, and clerical work without the help of a computer.
