Conditional on these advances in science, technology, and medicine it's quite obvious how badly many Western democratic societies have done (that's not to say there aren't also positive outcomes, and it varies a lot by nation).
Take the US as an example: Would you have guessed that the 'most pandemically prepared country' would lead Western democratic nations in terms of death count? How ready do you view US society to combat future threats like climate change, an even deadlier pandemic, or non-democratic state actors? What does that mean for the Western model of democracy?
