This was my understanding as well: That beyond ~7nm the reliability begins to lose value because the diameter of an electron 'orbit' or whatever becomes a factor.

Admittedly I'm not an expert. But my understanding was that to break this limitation and keep Moore's law were kinda leaning into quantum computation to eventually fill the incoming void.

The reason you mean is quantum tunneling. Essentially, at that small a scale an electron can 'teleport' outside of the system, which is obviously a big nono for computing.
