What does the phrase “Necessity is the mother of invention” mean?

Well, the point of this phrase is that, if somebody needs something, or is fed up with participating in a difficult task, then there will be people attempting to invent an object or a way of making the activity easier. If people didn’t need anything, then there would be no point in creating anything.
