This is clearly not the place to ask this question about mining. This is a thread about a software development on a whole different side of Bitcoin. If you are genuinely curious about the theme of your question, and not just interested in derailing threads, you are very welcome to educate yourself at bitcointalk, the main Bitcoin forum. There have been thousands -if not millions- of man hours in thinking, development, research and debate about the topics you enquire about. Head there and find the answers, and if still in doubt don't be afraid to ask (on an appropriate thread).
