No need to save the Planet. It should function well in the next 30-100 
years.
The Singularity will come earlier (~30). It will solve all problems.
We will get abilities to got new bodies, new mind, and new souls.
There will be no need to stay in the body of monkey anymore, we'll get 
ability to exist in any form, humanoid, virtual-mind, distributed 
systems (like skynet), pure energy, ... There will be no limits.

So, come back, don't be afraid to love Ruby. ;) The sooner Singularity 
comes the better, for all(also for Earth).
