Had to written this with English either I think.

Long story short, this post is about that we have to keep balance between copyright and motivation. If Apple didn't get ideas from PARC, we wouldn't have ideas of GUI, PC and others. So I think, as Jobs says, great ideas have to be stolen.

In further arguments, I think too much power for copyright law will inhibit latecomers to enter. In the other hand, too less power for copyright law will let front runners down. After all, balance is most important.

My English isn't fluent enough. Hope you can understand what I say and what I want to say.
