Thinking technology will always save us is no different from divine or magical thinking.

Lots of societies and civilizations have collapsed. Some were straight up wiped off the earth and we don't even know what happened to them. Western civilization has had a good 500 years, and America has had a good 250 years, but that doesn't mean things can never go bad in the future.

Plenty of places have had catastrophic droughts, famines, and plagues. Nearly half of Europe died a few times from plagues. Most natives in America were absolutely wiped out from disease and other issues. Tens of millions died of famine in China last century. Tsunamis washed away and killed hundreds of thousands in Indonesia and Japan this current century.

In the past, the Krakatoa eruption messed with the climate around the world and made the sky dark. The Bronze Age Collapse is something we still don't understand but nearly wiped out everything in the western world. With population density higher than ever, disasters that match major historical ones would be far more destructive. It's really just been an unusually peaceful few decades in first world countries and people have gotten too comfortable.
