If o3 can design it, that means it’s using open source schedulers as reference. Did you think about opening up a few open source projects to see how they were doing things in those two weeks you were designing?
E.g. pop songs with no original chord progressions or melodies, and hackneyed lyrics are still copyrighted.
Plagiarized and uncopyrightable code is radioactive; it can't be pulled into FOSS or commercial codebases alike.
The argument went that the main reason the now-ancient push for code reuse failed to deliver anything close to its hypothetical maximum benefit was because copyright got in the way. Result: tons and tons of wheel-reinvention, like, to the point that most of what programmers do day to day is reinvent wheels.
LLMs essentially provide fine-grained contextual search of existing code, while also stripping copyright from whatever they find. Ta-da! Problem solved.
