A preliminary estimate, and a request for better ones.
Summary
I believe the standard literature estimates for the number of DALYs attributable to a case of stunting are too low, largely because they don’t account for the long term effects. This means that childhood nutritional interventions that reduce the prevalence of stunting may be substantially more cost-effective than previously believed.

I think this is a good point, predictably enough--I touch on it in my comment on C/H/M's original post--but thanks for elaborating on it!
For what it's worth, I would say that historically, it seems to me that the introduction of new goods has significantly mitigated but not overturned the tendency for consumption increases to lower the marginal utility of consumption. So my central guess is (a) that in the event of a growth acceleration (AI-induced or otherwise), the marginal utility of consumption would in fact fall, and more relevantly (b) that most investors anticipating an AI-induced acceleration to their own consumption growth would expect their marginal utility of consumption to fall. So I think this point identifies a weakness in the argument of the paper/post (as originally written; they now caveat it with this point)--a reason why you can't literally infer investors' beliefs about AGI purely from interest rates--but doesn't in isolation refute the point that a low interest rate is evidence that most investors don't anticipate AGI soon.
I feel like a real economist now — I’ve got my first referee report to read the prior literature :)
My gut feeling is that it will increase, because it might lead to an increase in lifespan. That’s so far beyond what we can do now that I think marginal utility goes up.
Depends how much it costs to lengthen life, and how much more the second added century costs than the first, and what people’s discount rates are… but yes, agreed that allowing for increased lifespan is one way the marginal utility of consumption could really rise!
