Generally, I agree with what you are saying. However, there is one example of someone speaking to the opposite view which I also agree with: Marcus Zarra: https://vimeo.com/97058344 https://vimeo.com/97058344 I think the key there is that he is in somewhat of a niche: client-side iOS programming. By limiting the set of problems which he is reimplenting "from scratch" again and again, he has some hope of getting very efficient at the "from scratch" approach (he becomes an expert in that approach). I also think this approach is probably only realistic for very small slice of people (top-level talent whom are also lone-wolf contractors (no oversight, no collaboration)).
