@Doubting Thomas:
And with 7+ billion people on the planet and rising, inability of our species to breed is not a problem science is particularly concerned with at the moment. Why spend the time, effort, and money making artificial wombs when there are plenty of natural ones out there doing a fine job propagating the species?
That's... not really an argument. The thing is, the world's problems don't get solved in the order of humanitarian priority, even assuming we could get enough people to agree on what order that is. If we did that, we'd be sitting around for decades or occasionally centuries without accomplishing much of anything because it takes that long to come up with and implement solutions which the economically and politically powerful find acceptable enough to allow through. So in the meantime, while some people are spending those decades figuring how to get the big stuff through, other people are busy getting the "first world problems" taken care of. I believe that there will be artificial wombs long before the world-hunger-level issues are solved, because the world is run by flawed and sometimes very greedy and selfish human beings.
Do you want a world where the biggest issues get solved very slowly, and none of the smaller ones do, or do you want a world where the biggest issues get solved very slowly, and a lot of smaller ones are taken care of in the meantime? Trick question - even if you pick the first option out of some kind of principle, it's never going to happen. Because most people aren't stupid, they know that the world is run by humans, so they're not going to wait around for the big problems to get solved and tackle whatever they can. Also, occasionally, tackling certain small issues can help a great deal with one of the bigger ones.
(That's not even getting into the issue where "but world hunger" or similar arguments are often used to dismiss real, life-or-death concerns for some people. Because humans can be pretty bad at judging what's really important, especially when they're far removed from the pertinent issues.)
