What is confidence?
A hypothetical situation where 20 CEO's board an airplane and are told that the flight that they are about to take is the first-ever to feature Pilotless technology: It is an uncrewed aircraft.
Each one of the CEO's is then told, privately, that their company's software is Aircraft's automatic pilot system. Nineteen of the CEOs promptly leave the aircraft, each offering a different type of excuse.
One CEO alone remains on board the jet, seeming very calm indeed, asked why he is so confident in this first uncrewed flight, he replies "If it is the same software that runs my company's IT systems, this plane won't even take off."
This is Confidence!!!
