The cost, or our understanding of the cost? I don’t think diminishing marginal utility has been achieved in such a drastic way; I think that the old Peter Singer quote from which that number originated has been taken out of context for decades. I could be wrong, though!
It says that’s the GiveWell figure for bednets to save a life, presumably as of 2010. I’m not sure how much of the change is due to more bednets out there (which has been significant) and how much is GW feeling less confident about everything than they did in 2010. “Famine, Affluence, and Morality” doesn’t mention a specific number to save a life.
Note that this essay was written several years ago, and the cost to e.g. save a life from malaria has changed.

The Current figure estimated by GiveWell is $3,500 per life saved:
