This century’s biggest single change will be the voluntary mass movement of humans from their birthplace to somewhere else. Historically most humans lived, learned, work, loved, thought about and experienced life within a 20 kilometre radius from where they were born. For the fir.

The window between a signal arriving and it demanding a response is shortening. The biggest changes we’ll experience this century is already shaping strategy conversations in forward-looking organisations. Treating it as a future concern rather than a present one builds a preparedness gap that will have to be closed under pressure.

The most important question is not whether The biggest changes we’ll experience this century will matter, but how quickly it will matter in your specific context. Leaders benefit most from mapping the ripple effects early — not just the direct impact but the second and third-order consequences that arrive later and hit harder. That is the practical work of foresight.
