i suspect that "collapse" doesn't look very dramatic most of the time because the systems that surround us are very fragile and a combination of modest but sustained interruptions are enough to severely degrade their operations.
but at the same time, the failure of a system leads to changes in behavior and neighboring systems which might subsume some of the roles of the failing neighbors. for a current example, soldiers driving trucks or staffing hospitals. these temporary arrangements can end but they sometimes become "indefinite" and strain the reserve capacity of the society to respond in other situations. in rich places, there is a lot more of this reserve capacity to burn through and a large-scale "collapse" seems unlikely any time soon even if that is a safe bet long-term.
but what opportunities open up in a world of uneven and slow deterioration, where it becomes harder and more expensive to organize large-scale endeavors as uncertainty and chaotic elements ruin long and medium-term planning? and where the debris from failed prior modes piles up
