I'm not the expert but Gemini doesn't say anything exists besides the Voltera V-One (which obviously doesn't work for complex PCBs). I am imagining something like a PCB microfactory the size of a container (or even smaller) that completely handles PCB etch and drill, solder paste application, PnP, baking, and testing.

PCBA lines are largely automated as of today, issues start when you do high-mix work. Most time ends up being spent switching between jobs and programming machines, meaning that tool usage time is low.
