I’ve taken a few grad level history courses, enough where I feel “safe” reading primary sources, and assessing the relative quality of history-oriented literature. I like to read “dull history”, especially social and economic histories with focuses on labor.
I totally agree with your dad. The HN community likes to dis Malcolm Gladwell (for example) but reveres Harari and Diamond. They’re creative smart people, with interesting and sharp ideas.
They like to lean on history or sociology to support their sharp instincts. Their books are good to get a sense for their instincts, and how they’ve occasionally played out through history. But you should never read them as an authoritative account of history or sociology, and you should not seriously consider their historical references to draw conclusions about the inevitability of the future.
I‘ve recently been reading primary sources of intellectuals living in Russia in the immediate months and years before WW1. None of them saw the war coming. None of them saw the revolution. Each of them made bold, evidence-based predictions about the near future, and they were all wrong. Same with (brilliant) Soviet economists in the 80s.
I recommend reading these books for fun if they please you, but please do not think that they’ve given you a comprehensive or correct view of history, even for the specific events they describe.
