Lecture: Learn to appreciate legacy (Story about Zed)
Why it is important to treat legacy code with appreciation and respect — it somehow runs and there is no guarantee that new code will do a better job.
There is a lot of frustration among developers when they need to work with the old code, usually called “legacy”. But there is way more legacy code running than non-legacy out there in the world. Developers like starting from scratch but that is not often the case. If they want to successfully replace legacy with newer code they need to start with appreciation and respect for that legacy code because it somehow runs and there is no guarantee that new code will do a better job.
