Democracy is not the end point of mankind. There may be developments in many different directions in the coming centuries. Democracy has only existed for about 200 years. It started out with the American Declaration of Independence. The Americans got their ideas from the Europeans, in the main from the French, the Dutch and the British.

The critical thing about Western democracy is the fact that you usually have a transition of power without bloodshed. That is an enormous advantage. But still, democracy as we know it was only invented recently in the West, historical speaking. It did not really work in ancient Rome. It functioned for less than 200 years in ancient Athens.
