It's an interesting observation. Personally, when I look back at giants and read their biographies, I find the most interesting bits usually about how they were motivated, what drove them, how they overcame challenges and hopelessness, how they forged business relations - I think the least interesting part is their personal life and what they did to piss someone off or what they tweeted/told publicly. The latter is just typical soap opera of details that provide little value to me. The latest Steve Jobs movie primarily focused on the melodrama of his personal relationships and offered literally nothing about what made Apple succesful.
