Why so many programing languages?

It feels like every other week I read on HN about a new programing language I never heard before. I do not understand why so many people keep creating new languages instead of improving on the existing ones. Don’t we already have enough options to express ourselves? Are we really evolving/improving or just disrupting/fragmenting? What drives so many people to think they can design a better mousetrap from scratch? Are we going to get to the point that everybody will create his or her own language, which might compile into JavaScript? Can someone help me make sense of the situation? What am I missing here?
