Necessity is a mother of invention because when we need anything then we discuss about that . Friend I will give some examples to you in a early time the man want to some things to live then the man think then he discovered or invent the knife to kill the animals that is an example I give . At last I think yes and you
Funny, I was thinking about this and was about to pose this question until I saw it had already been posted. I think necessity has created the drive for the majority of man's inventions, but I leave room for tinkering, curiosity, and even accident as alternate "mothers of inventions". Inventions which are developed in response to defined needs probably have a higher probability of success and widespread use. In the modern world investment plays a key role and investors are more likely to fund product development when the invention addresses a necessity. We still see the occasional surprise invention that didn't result from a concerted effort to meet a need.
