The way we do calculus is based on Leibniz's style because it was an improvement and more efficent than Newtons and it has lasted 250+ years. The math types went on to bigger and better things, nobody has tried to change those basics again and again jsut to be different. > Notation evolved to efficiently represent new concepts.
