"Stick your finger in the water, now pull it out. See how much of a hole that left?"

I have heard this theory before, and I disagree with it. If people were that unnecessary, they wouldn't have been hired in the first place.

I describe it as the inkwell theory. "Stick your finger in the inkwell, now pull it out. See how much of a hole that left?" -- True. Not much of a hole, but you still have a mess on your hands.

Not unnecessary but not irreplaceable either. A business built around the concept of irreplaceable people will fail.

People, good bright talented people are necessary but they must be replaceable. Otherwise they have to be on call 24/7/365. As no human can endure that kind of pace for long either you have a replaceable workstaff or you will soon have no workstaff at all.

I think it's a great lesson about how small we all are, in the scheme of things.

Humility.
