Are Henri Fayol's principles applicable in 21st Century and please justify?

Henri Fayol's 14 principles of management are as applicable today as they were when they were first published. What is good about them is that they are top down principles and are essentially flexible and capable of being adapted for individual needs depending upon the specific circumstances. The difficult bit even in the 21st Century is to determine how to make use of them. As time has passed, organisations have interpreted the principles in different ways from the way that Fayol and organisations at that time may have interpreted them, but this is right and proper because circumstances were different in 1916. Fayol understood that there was no single ideal answer and the best approach needed to reflect the internal and external environment of that organisation at the time. Change happens and just like in the animal kingdom only the strongest and most adaptable survive.
