My favorite parts of the Three Body Problem books were the political and ideological commentary.
More than just because the books were fascinating science-wise, I loved these books because they really highlighted the dangers of anti-science, anti-intellectualism, fascism, class disparities, climate change, and more. Ultimately, (in my opinion) it wasn’t even Cheng Xin who decided the fate of the world, it was the constantly changing extremist politics, the lack of urgency to advance science, and the inability of the world to come together for the greater good.
I think that’s why I find it fascinating that people who very loudly believe in the exact dangers the books speak against love these books. I feel like some people just skip over actual messaging in the books.
