A Drexlerian singularity will alter discount rates. If people know that their
income will increase by a factor of 100 in the next year, it will take an
enormous interest rate to make them save. I believe Robin's model doesn't
account for the effects of insanely high growth rates
on discount rates.

A Drexlerian singularity looks rather odd in Robin's model. Basically
the savings/productivity function goes almost vertical at the singularity.

Robin: In your model, what happens if savings have increasing returns to scale
all the way out to infinity?
