You cannot perfect old languages. And you cannot write a new language without making architectural errors. And any new language that deviates significantly from what has gone before will only ever see niche success.
Thus what we have today is the best we can expect: gradual evolution of new languages, and gradual improvement of old languages. Neither has any particular advantage, but the industry as a whole keeps grasping at the eternal straw of the ‘silver bullet’ language that new languages promise.
