He's probably right.
I snickered at this, and I agree. Honestly, nothing Elon Musk sets out to do even impresses me anymore. It's just the standard he's set up for himself. It is interesting to see that Solar City was founded with his cousins. Elon understands the importance of family. He himself has like 5 children!
