Most IT geeks don't have the personal skills required to rule the world outside of their computer. I would however expect that more "world rulers" will start gaining IT skills in order to have more power and be able to do more things.
Now the situation is different. They don't need any personal skills.
1. They will have a lot of money to vote with their wallets.
2. They have the Internet using which they can communicate with other people and shape their minds (already happening)
3. They will have companies & lawyers at their disposal so they can push legislation they want.
