Historically, whenever there's advancement in technology. Powers that control the current will get challenged, and so far, it has been for the better for the majority.

We've gone a long way from being serfs who have almost no rights, even the right to read and write.. to citizens who can communicate via the internet.

Advancement in technology will/have make current powers obsolete. Robots and algorithms have been taking more work since the stone age.

Better tools, means more surplus, means more time to think critically, more time to comment over the internet, or read books.

The only problem is that we probably won't see any observable improvement in one lifetime. It is however, also very possible that the incumbent powers put an end to our civilization. Hopefully enough people like these Google employees, Snowden, Assange will be there to stop fascism.
