Actually since its already been discussed a 1% growth rate maxes out in 3000 years, your factor is off. Stop fudging the numbers.

Absolute crap. They already spend tens of billions on AIDS research, and havne't done jack. Thats an easy problem compared to nanotech.

Some civlizations may be much slower, some may have 'religious' reasons not to go further, esp. if they are long lived and have greater ability to naturally constrain reproduction. You are sounding like a Democrat baking the budget surplus higher to justify more social spending.
