The answer doesn’t actually lay out how electricity flowing through a bunch of NAND gates physically causes the computer/CPU to begin booting up.
There’s always a step missing in these types of answers,
step n: electricity begins to flow through gates
step n+1: ???
step n+2: Microcode execution begins
Presumably in step n+1 something happens to the chip, more than just heating it up, that causes a regular pattern which we would call the very first step of microcode booting up.
