It’s just a joke. NAND isn’t a software, it’s a bit operation (Not And) so 1001 NAND 1010 = 0111

It’s technically a “piece” of a software and is necessary for any addition and more.

NAND gate

What do you mean “build”?

That’s just a Wolpertinger in the wild.

Well, it’s not cardboard, but I am absolutely fascinated by euroboxes.

A europallet is 1200x800mm.

Then there are euroboxes of 800x600mm, 600x400mm, 300x400mm etc.

They are stackable, reusable and recyclable and come in different types. Fully enclosed, with lid, with grid walls etc.

Machinists use them as toolboxes, bakers to transport bread and veggie vendors stack have their products on the market in euroboxes.

Calm down, Adolf.
