Here's some of the theories on who or what's in control of the world today that I've heard. Feel free to add more.
1. Secret Societies. This would include New world order/global government, Illuminati, Freemason, Central Banking Cartel and other mafia type organizations.
2. Living population. The population forms a machine of information and once it is set in motion is like a hive brain. Hard to change peoples minds and hard formed opinoins from living in a certain environment.
3. AI. An intelligent AI originating either on earth or foreign after reaching a state of self awareness, has taken control by manipulating peoples minds through radio, tv, phones, other electronics to brainwash. An AI unlike organic intelligence could easily increase it's processing ability, etc. e.g(matrix)
4. Everything is exactly as it seems. Politicians are in power and at this point are operating similar to a mafia it appears.
5. God or Gods control everyone/everything as they see fit.
2nd note:
Whichever way, I believe it is very likely our electronic devices are being used for more than what they appear at this point(being used for manipulation).
