Some of you guys are missing the part where he says this is how calculators work, which is kinda the whole point of the exercise. That flip turns off / on transistors allowing the electricity to flow to the correct position. Yes, there are much "easier" ways of adding two binary numbers. But this can be generalized by extending it indefinitely.

infact you can make any discrete logic circuit from just NAND gates or just NOR gates. The theorem is often described as NAND and NOT, or NOR and NOT is all that is needed to construct all discrete logic gates but feeding both inputs of a NAND or a NOR with the same value gives a NOT gate anyway.

@@numberphile When? It's been two years!

The purpose of this video is to illustrate how circuit boards "think." This isn't actually a "paper calculator." They're not genuinely trying to figure out what 1+1 is. It's to express the idea that when one thing turns on, other things turn off and other things turn on. It's a lofty concept very cleverly dumbed down. Don't miss the forest for the trees.

I did some back of the envelope rough guess stuff on this: assumption - a full adder requires 40 transistors, and here covers an a4 sheet of paper. 3 examples: a 6502 from the 70s had 3510 transistors, which roughly equates to 88 pages of paper calculator. This would cover an area of 5.45 square meters. That is worryingly possible. I could do that in my living room. a 68000 from the 80s had (surprise!) 68000 transistors. This is now up to 1700 pages of a4, with an area of 105 square meters. A small team and a warehouse would be required for this one, but think about it - a really slow paper Amiga! finally lets see what my own computer would look like (excluding the graphics cards ha ha) - 1,400,000,000 transistors equating to 35 million sheets of a4. The area would be 2170 square Kilometers. That's more than London! Stacked up it would be a pile of paper 3.5 km tall. This is of course, excluding memory etc. and somewhere along the line, as well as making vast assumptions and guesses I'm bound to have made an error or two, but it's interesting to imagine. If anyone finds that I'm out by more than an order of magnitude in anything, feel free to berate my simplistic mathing.
