Elon Musk taught himself computer programming at the age of 12, so he is familiar to the concept of self study.  

You have to remember one thing, he founded X.com, an online payment company and they later merged with

Confinity in 2000 and became PayPal. So he has very intricate knowledge about online payment systems. I should think that

he would be interested in new ground-breaking technologies in the online payment scene.
