Q: to AI.

So what is the most constructive comment I could make on this article that contains the core of its argument?

A:
The article makes a valuable point that extends well beyond the relative merits of waterways, rail and other transport corridors. Physical connectivity is only part of the equation; the real test is whether the political and institutional arrangements surrounding that connectivity are reliable enough to make it work.

In that sense, the European Union is an important experiment in addressing precisely this problem: reducing the political, regulatory and commercial uncertainties between neighbouring countries so that infrastructure can function as a genuinely integrated system.

But the article also highlights the limits of that achievement. A river, railway or port can remain physically intact while its strategic and economic value changes dramatically when political relationships, regulations or security conditions change.

Perhaps the deeper lesson is that infrastructure can connect nations, but only institutions can make that connection dependable. The efficiency of a corridor is therefore determined not simply by engineering or economics, but by the weakest political or institutional link in the system.
