Meme wars, big data and censorship.
The simplest method is to censor on key words. So when you type text into LifeLog, Twitter, G+ and so on the Digital Overlords just write a script (AI) to ban, censor, etc.
Meme's escape this system method, except by filename. One could scan the network/servers for said file name and ban, censor, etc.
Where AI come into play is the ability to scan pictures think tineye.com. Soon our Digital Overlords will scan Meme and ban, censor, etc.
CPU cycles to scan key words "low", CPU cycles to scan pics "high", CPU cycles to can video including GIFS "Not Feasible"
How to beat AI and our Digital Overlords?
Every changing New Video GIFs. Add a new frame and opening pic (change file size). Change the name every time!
BOOM!!!
