There are different arena's one can code in. No one is going to die if their word processor crashes. In such a situation one is free to choose another word processor.
If a service is being contracted for the people from a government and human health issues are at hand then the people have a right to require that the engineer, whether he be a civil engineer or a software engineer, has proven to them that he can complete the task with safety and has the skills to show them the numbers that make it safe.
This is akin to verifying the correctness of code (mathematically proving that it cannot fail), an incredably extensive and expensive process. But sometimes it needs to be done. An exam such as the Professional Engineer exam is an attempt at making sure the people who work on these projects that affect the public know when and how to do this.
Testing code relentlessly is one thing, verifiying it's correctness is another.
Or use 2 pieces of glass that were different densities. There would still be some phase cancelation, but as the denser glass would need less movement to reverse the image phase change, the sound wouldn't be completely cancelled. Also a vacuum could be placed between the 2 pieces of glass, limiting phase cancelation even more.

They each have their arena.
