  • Computers On The Other Hand Back To Back Human
    428 words
    I'm sitting down at a computer that has very vast capabilities. It is capable of almost any application, but it being only the size of my history textbook, leaves it fragile and vulnerable. With a few light slams, or the pass of a powerful magnet, it's very existence could be destroyed. Ancient times suggest not only survival of the fittest, but also survival of the smartest. Long ago the dinosaurs went extinct leaving many of the bigger brained mammals the dominant species. Then the larger brai...

In the essay it was stated that object-oriented pr...
