India,

One thing is clear. World will progress, with or without India.

I am fairly optimistic about capability of humanity to survive and flourish.

Also future religion will be in harmony with Indian experience, the details may vary, even if all that is Indian were to vanish, loss of knowledge is not permanent.

Evolution being convergent as well as recurrent.

At most there will be a setback of millennium, give or take some hundred year, which is insignificant on the scale of human evolution much less cosmological time frame.

World can survive without India.

The concern is not world, it is India. I want India to succeed, to be leader in that future world.

And there is nothing rational about, it is what one might term genetic affinity or tribalism. May be Indian civilization is beyond redemption, may be USA is the promised land, but we will never know unless we have tried and failed.
