That's not the point. It's not walking, it's planning. When all you have are rocks and spears it doesn't matter how far you can plan. When you have nukes and other people's lives in your hands, it does matter. Like, any of the recent wars. What kind of planning went into those stalemates? Evidently none. What about inflation? Still unsolved? Undoing all the green energy efforts made in the past? Well done, apes of Africa, well done.
