Elon Musk is easy to read for anyone who is a Robert Heinlein fan. He is creating his own version of ‘Howard Families’.

[..]The books Time Enough for Love and To Sail Beyond the Sunset tell the stories of two famous Howard Family members: Lazarus Long and his mother, Maureen Johnson. Lazarus Long also appears in The Number of the Beast and The Cat Who Walks Through Walls.[..]

To understand Elon Musk (and predict future trajectory), Stranger In A Strange Land is a good start.

He is a textbook nerdy sci fi loving teenager trapped in an adult’s body. Turns out it’s that not bad for humanity.
