|What if Operating Systems were Airlines?|
Everyone brings one piece of the plane along when they come to the airport. They all go out on the runway and put the plane together piece by piece, arguing non-stop about what kind of plane they are supposed to be building.
Everybody pushes the airplane until it glides; then they jump on and let the plane coast until it hits the ground again. They then push again, jump on again, and so on...
All the stewards, captains, baggage handlers, and ticket agents look and act exactly the same. Every time you ask questions about details, you are gently but firmly told that you don't need to know, don't want to know, and everything will be done for you without your ever having to know, so just shut up.
The airport terminal is pretty and colourful, with friendly stewards, easy baggage check and boarding, and a smooth take-off. After about 10 minutes in the air the plane explodes with no warning whatsoever.
