Why will hacking always be a part of information and technology?
Sun Tzu said ”there are only 5 original [musical] notes, but they can be combined in an infinite amount of ways”. To a skilled hacker with the proper utilities, there is always a way in. There is an infinite amount of ways a system can be compromised or secured. In a broader sense, a hacking/programming project is never truly finished (#5). Infosec will always be a perpetual game of cat and mouse, but therein less the beauty of it all.
Constant change. Plenty of room to better yourself, your system, and your education. Hacking is the perfect opportunity to be accepting of constant change.
