Despite the contradictory caption More Code, Faster is making a point for less code (typed by humans). Of course, Dan Creswell concedes that this comes at a price:

The less code philosophy requires doing some design, pausing for thought and not cranking code. It can provide massive benefit but it’s difficult to measure in any simplistic fashion and thus is seen as pure cost by many.

So, if you’re lucky enough to get it free, why one has still to argue in favor of less code?
