You can use NAND to make NOT.
That's quite unexpected. Thanks.

But... you have to know what a derivative is for in order to be motivated to learn how to do it. If it's all just mindless manipulation, how will one know whether to apply this or that mindless manipulation?

It's an optimization. You really could build the whole thing from NAND gates if you really wanted to.

Thanks, that page is nice, but it too emphasizes that you also need a clock. That's essential and it was the point I was trying to make. For example, a thing that is usually glossed over in OS courses (in favor of, let's say, scheduling algorithms and such) is that you simply can't make preemptive multitasking out of pure code - and later when you ask yourself how is it that such a phenomenon is possible in the first place you learn that chips are inherently parallel, that sequential code is an abstraction over that so that one can have some sort of law and order, and only then interrupts enter the scene so that one may break that order when needed, e.g. for preemption.

The title of the course is misleading, as it suggests that NAND gates are the only required primitive, whereas the course later introduces DFF gates, without which you cannot escape the parallelism of chips.

Don't forget Google X (the original one)!

For a long time, I thought he and Joseph Campbell were the same person (as in "the mentor of Asimov, the one with the hero's journey").

I read that as: less syntax, less leaky abstractions and less macros; and I mostly agree.
I would add better integration with the C tool chain, more separation of concerns and less academic ego bullshit.
I've been working on something like that [0] lately.
"an embedded Forth with a Lisp in C" :)
Sounds like the opposite of what the post is advocating.
