We definitely don't. Unfortunately, there's groups pushing to erase history that they don't like. The dark eras of human history. I say that's the history we need to remember and learn from the most. A big part of progress is knowing where you started.
Another big issue, at present, is measuring things that happened in the past by modern standards, then getting incensed/outraged.
I love WWII history, maritime history, and a bit of aviation history (love the SR-71). Also power generation history and industrial history.
Something I read the other day resonated:
In evolution, there has never been a time in history where man has ever gone from one source of energy to another that was less dense. The industrial revolution was driven by our mastery of fossil fuels (coal, oil, gas) that enabled a dramatic expanse that rapidly increased quality of life, and this was the foundation for modern society. We went from mostly low energy agroagarian pockets dependent on sunshine and breezes (no industrial farming, wind mills, sailing ships...etc) to one that could run 'round the clock no matter the weather.
It was logical then, that, the age of the atom would be the next step. Subs that could stay underwater as long as the wanted, carriers that could circle the globe for decades without refuelling, a source of power that was 20,000x more dense than what came before it.
So it's interesting to see this bizarre flirtation with malthusianism and degrowth, attempting to take us back to the days before modern medicine; to before the industrial age and that there are people that are wholesale invested in this fantasy and ignore the massive extractive nature of trying to bring this spectacle to life.
