Hoy estuve leyendo una entrevista de Technology Review a Bjarne Stroustrup y estos son algunos apartes para que usted decida si tambien le gustaria leerla
Technology Review: Why is most software so bad?

Bjarne Stroustrup: I think the real problem is that "we" (that is, we software developers) are in a permanent state of emergency, grasping at straws to get our work done. We perform many minor miracles through trial and error, excessive use of brute force, and lots and lots of testing, but--so often--it's not enough.
Software developers have become adept at the difficult art of building reasonably reliable systems out of unreliable parts. The snag is that often we do not know exactly how we did it: a system just "sort of evolved" into something minimally acceptable. Personally, I prefer to know when a system will work, and why it will.
TR: How can we fix the mess we are in?
BS: In theory, the answer is simple: educate our software developers better, use more-appropriate design methods, and design for flexibility and for the long haul. Reward correct, solid, and safe systems. Punish sloppiness.
In reality, that's impossible. People reward developers who deliver software that is cheap, buggy, and first. That's because people want fancy new gadgets now. They don't want inconvenience, don't want to learn new ways of interacting with their computers, don't want delays in delivery, and don't want to pay extra for quality (unless it's obvious up front--and often not even then). And without real changes in user behavior, software suppliers are unlikely to change.
