The phrase “The cost of doing nothing” is common in finance and climate crisis debates, but it sparks ideas for me in other areas, both personal and professional.

On climate, the tone is alarmist—and likely with reason—arguing that if we do not act urgently, the problem doubles every few years until no force can stop it.

It is about “bad” inertia: once the train picks up too much speed, we cannot stop it from the platform with bare strength.
