hold_my_fish’s setup in which there is no increase in growth rates, either destruction or normality, is not the same as my discussion. If you include the third option of a high-growth-rate future (which is increasingly a plausible outcome), you would also want to consume a lot now to consumption-smooth, because once hypergrowth starts, you need very little capital/income to smooth/achieve the same standard of living under luxury-robot-space-communism as before. (Indeed, you might want to load up on debt on the expectation that if you survive, you’ll pay it out of growth.)

The math in the comment I linked works the same whether the chance of money ceasing to matter in five years’ time is for happy or unhappy reasons.
