Re: In what world
Anything that encourages more code reuse also encourages not knowing exactly what the code you constantly reuse does behind the scenes. Like many things, its a tradeoff.
At least one thing in the "favorable" column of the tradeoff is that if a bug is discovered in code that is reused in many places, it only needs to be fixed once. If everyone is reinventing the wheel, many bugs will need to be fixed over the years.
