Necessity is the mother of invention/ innovation

[Mnemon]

a. Necessity is the mother of invention.

b. Necessity is the mother of innovation.

Are they both common in your neck of the woods?

Thanks.

It's a. This is a common proverb.

 

[probus]

Not only is it a, but b isn't even true. In the 1960s we didn't feel a need for personal computers. Now we find it hard to live without them, but nobody demanded that innovation back then.
