MeowersJubei HimuraMeowers21st, 34th... Still humans with the same pattern of flaws.
I mean, you could say the same comparing 7th and 21st... well, maybe we're a little better.
And why not? Science and tech are improved during the time, but it's still the same human society. With flaws haven't gone, but transformed over time.
I'd say our more concrete grasp on reality through science, and all the benefits that's provided, has been a strong net positive on human society.
Superstition has lessened, knowledge and freedom have increased. There is much work to be done, but we're further along than ever.
