Can Pune surpass Mumbai economically in the coming 10 years or 50 years?

The reason Mumbai has grown and is still growing is because of its cosmopolitan nature. Pune on the other hand is less cosmopolitan with a large stress on Marathi manoos sentiment. For any city to grow in India, with its diverse population, it has to attract the best of talent from all parts of the country and the world. Given Mumbai is known in the entire world, it is definitely the choice of talented people across the world. Pune, no, it cannot surpass Mumbai, economically or otherwise in a zillion generations.
