Hacking is to different each person, by hacking I mean being able to do something you normally wouldn't or shouldn't be able to do. Not like illegaly hacking into a site, but breaking code that 'would' allow you to get into a site with a specific vulnerabilty is. For example, I may 'hack' into my own network to simply see if I am vulnerable and if so then I can figure out a way to fix that so it doesn't happen again.
Or for another example of hacking, which means to mod or alter something:
Our next video will be on 'hacking' video game consoles, it is to change or 'alter' the state of something, and so I will be 'hacking' it. For instance, one of the mod's is to simply change the case of a GameCube to make it so it can play CD-R's, DVD-R's, etc. And with whats known as a 'boot' loader, you can then play imported games, which having modded it with that special case, I don't have to pay for Mini-cd's, etc. Which is in no way illegal, same way I can play a BACKED UP game on it now. Thats not illegal either.
Yes, hacking can be used for bad and for good, but so can guns, bombs, and even butter knives. It is all how you use it. To close your mind about hacking, is to be judgemental without any facts at all. Learn about something COMPLETELY, before you ever speak of it again.
Therefore hacking can be used with ANYTHING, old or new.
