This true but also irrelevant to the point that technological supremacy doesn’t equal a guaranteed win.

Every place mostly populated by people is bound have a lot of idiots.

You’re not wrong. This is one of the ‘other things’ I mentioned. A shortage of natural resources is another. Winter, too.

But it is not a myth that Germany had many high quality, but incompatible weapons systems from different manufacturers (handguns and rifles) and that e.g. the tiger was impressive but unreliable.

The best example might be the Wunderwaffen they shot London with. Useless in the grand scheme of things, yet technologically impressive.

My point is that technological supremacy isn’t automatically going to secure the victory.

Keep in mind that the Nazis back in the day had sophisticated weaponry and a lot of high quality stuff, but they were beaten by cheap, mass produced, easy to use weapons and armor. Among other things - but the point still stands.

They’re not all identical in size. Maybe football fields are a better example
