My question is this, do you think the ability to curb death will be universally available quickly or will it take many years for it to be available widely?

I think the emergence of our next system will take a mere decade to diffuse (I think this will include the system structures and technologies to keep all agents alive). My reasoning for a decade diffusion time of the next system is based on extrapolations of previous system transitions. The hunting transition took hundreds of thousands of years; the agricultural transition took tens of thousands of years; the industrial transition took centuries; and the global brain should emerge in a decade.

In other words, by the 2040's should I be setting aside money now? My singularity savings account?

It's a personal decision of course. I personally think that a global brain system will be one that is also post-scarcity (or even one of radical abundance) - so it may be a system that doesn't require such a thing as "retirement savings" (since I don't really know whether people would be retiring).
