The infrastructure, agricultural optimization, crop cultivation and breeding, city growth, and other technology that supports the several billion people that are alive today was built over the last century. The capacity growth is also exponential, so the relevant infrastructure is on an even shorter timescale than that. Global ecosystems are also far more stressed from the load of humanity than they were 100 years ago. The regenerative capacity of biological systems responding to that system is not simply "barely at capacity", it is in a negative state. On top of that, we will be accelerating the rate of average temperature changes, in a time when access to weapons of mass destruction (ones that are orders of magnitude higher than what existed 100 years ago) are higher than ever. The nature of exponential growth and what it does to fixed capacity regenerative systems is certainly difficult to internalize. Cracks form over time as stress is absorbed. Collapses happen fast. The transition between the two is hard to time.
