"Everything is just" approaches usually result in hammering things that don't fit into fitting. That often ends badly. Computing has been through, at least:

- Everything is just a function (SICP)

- Everything is just an object (Smalltalk, and to some extent Java)

- Everything is just a closure (the original Common LISP object system)

- Everything is just a file of bytes (UNIX)

- Everything is just a database (IBM System/38, Tandem)

OP here. I would add "All you need is NAND".

"All you need is Transistor" - can't believe how badly that ended!

It's because all you need is Ohm's law.

James Clerk Maxwell has entered the conversation

Ohm's law doesn't really work for transistors though.
