I agree that the pull out jokes are funny, but Musks's kids are mostly IVF, and he is over 50, and most of the women are on the older side too. So yeah, very high likelihood of abnormal psychological development in most of his kids. I dont think repopulating the planet via IVF with old sperm and eggs is going to work out the way Elon thinks it will.

Also, I think it is one of those open secrets that Heard's daughter was made with his sperm, so the unofficial count is even higher than the official one.
