Yes, but we are one proverbial red button away from nuclear hell on Earth no ancestor could have prepared for, where a lot of anxiety will translate into a lot of lives being saved. So we’re not too far from being adapted to the modern world. It’s just that temporarily things are going well - there are no famines, no lawlessness, and no wars. As soon as we return to chaos even a bit, all those thrifty genes and anxious genes won’t be so maladaptive. There doesn’t even need to be a world-ending scenario. Just go live outside an urban center, among wild animals, and all these genes will help you.
