first of all, you say 'every single thing'. that is your first mistake. i didn't suggest something like that. learning about GPFs so that you understand about memory protection is not 'every single thing'. 'one more thing', maybe.
why bother? well... first of all so that you don't reach to conclusions about things you know nothing about. if you bothered to read about this, you would know that accessing, or worse, modifying the content's of a program's memory is not something that can be easily bypassed. if it were, the first stray pointer would just garble everything in your computer.
in short, you have the skript kiddie attitude. (i know how to press edit to edit memory and it works, so why would i want to know everything about my pc, since i got this tool to do the work)
