The concept might frighten you, but as the chaos theory also predicts: you probably do know the direction where it is going, and the only thing you can't predict is the sole high-frequency feature of _the_ event that will cause the sudden change.
So it has nothing to do with a "single event", but rather the "pre-conditions" which allow for that single event to evolve into such consequences. Don't blame an idiot who broke a brittle system.
I agree that a single event that causes the tipping point doesn't really matter and knowing the general direction things are going is helpful. This does not mean necessarily though that you'll have any ability to change it. Even if you had the power to change anything, it assumes you actually know the correct actions to take.
