an idealist view (Score 1)

I'm currently pursuing an accelerated masters in computer science, I may be naive but i feel my view is valid. Open source is the future, well commented and the most efficient code should be made open source. Why rewrite code that has already been written efficiently? Allowing access to well written and commented code to the masses will allow for much more competition between coders. I understand it is not the easiest of jobs, but wouldn't it make it easier if coders had some sort of universal code library where the best(efficient and stable) code is up for use to create great applications and is also up for optimization and improvement?
