I completely agree. This also applies to engineering, though. If you are making a gingerbread house with your child for a school project, you are not going to need any kind of certification. If you are building a shed in your backyard, you may need a permit, but you do not need extensive approval from quality assurance teams on each step of the process. Software is the same way. Large systems require more extensive testing. A space shuttle needs software and engineering with extensive testing. A bridge and software for medical devices needs quality assurance beyond the usual scope. However, quick hacks exist in engineering and software, and it makes no sense to 'trust your code with your life' or 'trust your engineering skills with your life' when all you are making is a popsicle stick house.
