Or if any other kind of progress (including moral progress, some of which will come from future people) will eventually abolish factory-farming. I’d be utterly shocked if factory-farming is still a thing 1000+ years from now. But sure, it is a possibility, so you could discount the value of new lives by some modest amount to reflect this risk. I just don’t think that will yield the result that marginal population increases are net-negative for the world in expectation.
