Beauty is more important in computing than anywhere else in technology because software is so complicated. Beauty is the ultimate defence against complexity.
The unavoidable price of reliability is simplicity.
Complexity kills. It sucks the life out of developers, it makes products difficult to plan, build and test, it introduces security challenges and it causes end-user and administrator frustration.
Simplicity — the art of maximizing the amount of work not done — is essential.
From the Agile Manifesto
Simplicity is hard to build, easy to use, and hard to charge for. Complexity is easy to build, hard to use, and easy to charge for.
Increasingly, people seem to misinterpret complexity as sophistication, which is baffling—-the incomprehensible should cause suspicion rather than admiration. Possibly this trend results from a mistaken belief that using a somewhat mysterious device confers an aura of power on the user.
Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage — to move in the opposite direction.
The computing scientist’s main challenge is not to get confused by the complexities of his own making.
E. W. Dijkstra
Complexity has nothing to do with intelligence, simplicity does.
