Comment by Zhongshi Xi on "Bug-free software in the future! Possible or impossible?"

The reason that a bug can appear is due to human itself In my past 2 years I have produced bugs which of root causes can be:

Bad emotion or being too much stressful which affects your approach to solving problems, in this state, you are likely not to be considerate.
Simply did not pay attention to details
you think your code is good - but not good enough, this is basically due to that you do not know there is something you do not know.
business requirements - too complicated and not well broken down into smaller pieces

Can technology help with it? I do believe technology can facilitate people to write less bug.

Can technology totally remove bugs? Anything that technology can replace must be specific, repetitive and accurately quantifiable. But since various people produce various types of bugs, personally I do not believe technology can remove bugs ( But I wish I could be wrong ).
