I don’t think it’s the electrons moving that matter. It’s the electric fields, which in conducting materials, is approaching the speed of light.
The latency you’re thinking of is more related to the speed with which a semiconductor can change from conducting to non-conducting states.
The speed of electrons in a wire with a potential difference across is it is actually quite slow (cm/s or so).
Also, modern chips and electronics aren’t significantly larger in a physical sense, the wires/traces aren’t longer, but the density of transistors has increased.

Someone please correct me if I’m wrong.
