I read Nietzsche after rand and I thought his philosophy had some similarities to rand but from a more emotional perspective. They say very similar things about being yourself and being selfish, but one from rationality the other from emotions.
For me the difference between musk and Steve jobs demonstrates this. One is an engineer entrepreneur the other an artist entrepreneur. Both incredibly successful but couldn’t be more different, but of course both are assholes too and took what they wanted from the world.
