"Pick the right ones, and programming will flow naturally from design; 
modules will have small and simple interfaces; and new functionality will
more likely fit in without extensive reorganization. 

Pick the wrong ones, and programming will be a series of nasty surprises: 
interfaces will become baroque and clumsy as they are forced to accommodate 
unanticipated interactions, and even the simplest of changes will be hard to make."


MIT Professor Daniel Jackson

A comment that sheds light on this comes from Steve Jobs, CEO of Apple:

When you start looking at a problem and it seems really simple, you don't really understand the complexity of the problem. Then you get into the problem, and you see that it's really complicated, and you come up with all these convoluted solutions. That's sort of the middle, and that's where most people stop....

But the really great person will keep on going and find the key, the underlying principle of the problem—and come up with an elegant, really beautiful solution that works.

That's what we wanted to do with Mac.
