How do you know that your text editors aren't compiled to hide the payload when examining this compiler, thus perpetuating the hidenness?
The ultimate question is: How far do you need to go until you believe that the earth is indeed not flat? Do you trust your teachers? Stand on a tall building? Take a balloon ride? A plane? A spaceship? Then still, at which point can you rule out that the earth just appears to be a ball due to some yet-to-be-explained phenomenon (gravitational anomaly?) but is indeed flat? (The correct answer of course is "turtles all the way down").
