You referenced and tried to refute the article, but how do you know Musk is happy? How do you know he has found his personal balance? From what little I know about his personal life -- and it may be unrepresentative, again -- you can argue his personal life is on the rocks. He might also be perfectly happy. But what's the evidence? I don't see any evidence his story supports you point at all.
You're right -- we don't know. My interpretation of the article was that the AUTHOR seemed to imply that that was unbalanced, and my point in bringing it up was that it didn't seem right for the author to critique what is a balanced/not-balanced life, since it's different for everyone.
You keep equating "balanced/not-balanced" with "good/bad".
What do you mean by "balance" if you don't mean the normal definition of "engages in activities/pursuits from all aspects of life"? By the normal definition of balance Elon Musk is not leading a balanced life at all, but a dedicated and focused life. This is not a value judgement, it's perfectly reasonable to make that choice.
This idea that balance is different for everyone makes me think you are using balance to mean "fulfilling" or "happy"?
