I disliked the books and haven’t tried to watch the show.
But I think I disagree that our civilization is no longer capable of solving it’s own problems. Rather, I think our civilization is going through one of the crappy parts of common cycles that civilizations go through. Frighteningly, this part usually comes right before really scary crappy parts.
Civilizations aren’t static and the patterns don’t always happen the same way, but I think we can predict that
Things get really shitty. People pull together for survival and build to a place of stability and prosperity.
The rich and powerful (being short sighted idiots just like the rest of us, but ALSO insulated from and out of touch with reality), start looting society for their own selfish, short term benefit. This destabilizes the institutions and systems creating the stability and prosperity. The population at large doesn’t really understand what’s happening or why, but they DO know that while they’re still relatively comfortable, they’re scared and they don’t like it. They get more conservative and eventually turn to fascists, strongmen and authoritarians to try to get stability back.
This doesn’t work out. It exacerbates the existing problems, makes things even more scary and less stable. Eventually war and rebellion break out.
When the dust settles, things are really shitty. People pull together for survival and build back to a place of stability and prosperity.
These steps aren’t exact. They’re trends. Lots of things can disrupt them (including famine, plague and barbarian invasions). But in step 1/4, we (humans) are actually REALLY good at collectively solving problems. In step 2 we’re TERRIBLE at collectively doing anything. In step 3 we (collectively) are trying to solve all the WRONG problems… then back to step 1/4.
We seem to globally be right at the tail end of step 2. Which SUCKS.
tl:dr; This has all happened before and will surely happen again. Hostile aliens are just a modern take on the “barbarian invasion” disrupter. Beware of strangers bearing gifts.
