The beautiful thing about electronics (and hydrolics) is their inherent 1 dimensionality (although you can create higher dimensional interconnections). Electrical components in particular can be spectacularly linear (capacitors and log-lin diodes) over 4-8 orders of magnitude. The great thing about transistors is their localized non-liniarity (gain)... which was used to create simplified digital systems from analog circuits. This allowed fan-out and noise tolerance... which allowed more complex abstractions, processors and OSes to be built on top them.
