I don't think this is a fair comparison, software development is very complex, but an electricians job isn't, it's very simple but it's high consequence.

Software development may seem simple for a lot of people here on HN, but trust me, I can do the electricians job easily, but an electrician won't be able to do my job. The regulatory environment which requires the "apprenticeship" is a totally different topic and doesn't inform anything on the skill required to do the job. Also, the electrician apprentice gets paid while learning on the job, the software developer in training doesn't.
