Manipulation of our own species to survive extremes ...
that is underway....

I don't think it will take a 1000 years...

Our time is limited on a ...our expiration date was set when the planet was made...
there are and always have been finite resources here.
How we make use of them will dictate how much time we have.

As the expiration date is hastened...the efforts will move faster still.

Genetic Manipulation of the species is just one avenue of survival...
We are looking and studying many different avenues...
Some working alone some working with others...
Some will undoubtedly become dead ends....unless a different tangent of study finds merit with parts of the process.

The converging technologies ...or singularity ...offer as many unforeseen hopes as horrors...

It is anyone's guess who the dice will turn up...
