I read and loved that book however nowadays I highly recommend playing the game “Turing Complete” instead.

It does a fantastic job taking you from nand gates all the way to function calls but in a delightfully interactive way. Instead of just imagining how it all must work in ur head as u read, u get to build it.

I went so far as to build a little simd/gpu that drives an led matrix with my own cpu assembly and programmable shader language.
