I will disagree with your copy and paste assessment. While it will hinder a junior programmer its a godsend to the senior developer. Someone who can quickly recognize what the code is doing and integrate it into the final solution.

There are more than enough APIs just on the platform I work with daily that I can imagine how much fun it must be sorting through all those available to Windows developers must not be a joy. Well Google lets me search quickly for established solutions and combined with my knowledge I can quickly identify which if any will do what I want to do and adapt if not drop into my coding style.

TL;DR

Copy/Paste might not be good for new programmers, but time savings for experienced programmers warrants its use
