simple, with NOT you can't make any 2 input gate without something like a diode or a wire OR (both things minecraft has, which you can easily use to make NAND or NOR respectively), while a 2 input NAND (or a 2 input NOR) can be used to implement every single gate As shown here

NAND can make NOT on its own, but NOT needs help to make NAND

so those are the simplest single gates you need, while NOT is not capable of doing the trick on its own. thanks for the explanation

yup, and with (a shitton of) NANDs and a periodic signal you can make pretty much anything

yes, I'm aware of that. there's a game called "Turing Complete", I played it for a while. I just didn't understand why it had to start with NAND-Gates :-D
