You see, building something that works takes a lot of time and effort. Things stop working in a hurry, but making a replacement takes time, resources, and, most importantly, stability. This can only be done ahead of time, and doing so takes practice (by which I mean learning from one’s own plentiful mistakes).
The comments are worth reading as well.
