There are part of computer science and engineering dealing with well defined problems. then it is easier to judge solutions to problems by proofs and test cases. Whoever can't prove their code is right or writing test cases are really criminal in their professions.

But there are another part of computer science and engineering dealing with fuzzy requirements or unknown problems. I don't see any better way to explore that area except trials and errors and the scientists and engineers have to face possible charges of "piss-poor", unethical, criminal and evil for the consequences of their solutions.

I feel that you have a very clear dichotomy of moral system. Unfortunately I deal with fuzzy things daily and see the harms of dichotomy in creating new stuffs and burning through money without any fruit of labor. It is easy for you to improve existing technologies because you can define criteria for improvements. But it is so hard in underfunding web startups that you can't expect in advance what a new solutions will be to users unless you make it and test it with them.

If I need someone to preserve and maintain existing software systems, because specifications and use cases are well defined, people like you are well fit for the task. But if someone has a new idea to solve a new problem that no one solved before, I would rather to see an unsophisticated solution first to test against the problem and start from there, and I am ready to rewrite the system when the problem becomes clearer.
