I wonder whether he never knew that breeding includes females, also for the next generation. He wants to have many, many sons, but how are they to keep up the breeding when they come of age when he has outsourced women of their age? His breeding plans are ridiculous!
I’m fully convinced he does IVF so he can selectively have sons… And it’s also why he’s so incredibly shitty to Vivian (his trans daughter) because she breaks his “only sons” plans. And Vivian is a constant reminder that even with all of his money and power to bend the natural selection process to his will via IVF, he can’t control individual people or stop them from being themselves. He just wants an army of mini-Musks, and Vivian flies in the face of that.
I believe she has stated part of his resentment is that he used ivf to ensure she was born male.
TLDR; he paid off people and they gladly took his money while the world burned.
