Yes, that's true. What we have not seen yet is the backside, or decay side, of that arc of history. Population ballooned to 8 billion, when energy becomes more scarce, famines are sure to arise. Populations in the most developed countries are suffering several profound problems: 1. very bad health both physical and mental as both the food system, and the environment become clogged with carcinigenics and other debilitating chemicals. 2. declining reproductive capacity. 3. Growing disapproval of authoritarian governmental arrangements that impinge on authentic freedom. 4. A growing economic impoverishment as technology aids the economic winners to extract ever more from the economic losers. ex: Gen Z is unable to buy homes as easily as their parents did.
I think the beneficial side of the I.R. reached its zenith in about 1969. The West is still able to prop up their economies - but the trendliness do not look good.
