think about how much more the human race has to do now a days. People say were lazy, and yes I realize people had to go hunt for their food and build their own houses and all that, I get up at 9, go to school and do all my homework and my last class ends at 7, thats what I do 5 days a week, I work at the shop when im not at school, so theres my weekend. I have to study for my exams inbetween that. Its gotten to a point where there is not enough time in the day to do everything if you want a good nights sleep, for a large majority of people at least.
And ur gona tell me that school has gotten easier since time has gone on? Theres more taught, and faster. Yes we have calculators and all that, but that only goes so far. So ya, if something is going to make life less stressful and help to do better and suceed, esp with all the competition in teh job field you've gotta stay on top if you want to do well, then why not use it?
Its the same reason you use a drill instead of a screw driver.
