A mammal reaches maturity from a biological perspective when the female of the species is capable of reproducing. The startup ecosystem in India has reached maturity as well using this metric, because we're seeing that people who have worked in the first generation of IT startups in India - companies such as Infosys, Justdial and Naukri - are now starting their own startups. Even better, the founders of these companies are new acting as angels and mentors to fund and kick start the next generation of entrepreneurs.
This is a very healthy trend and it's great to see that we are evolving in the right direction, rather than going extinct. This is the way both capitalism and biology work.
