Everybody knows that Santa employs elves to help him build his toys. Traditionally, they use hammers and other tools to build toy trains, dolls, horses, etc. As more children were asking for electronic toys for Christmas, the elves presumably started reading hammers in for soldering irons to build the circuit boards.
But nowadays, computers, video game consoles, phones, and other electronics can have processors with billions of transistors. As skilled as the elves are, I can’t see their skills of handcrafting toys to be able to create something that complex.
Assuming that Santa wants to keep his elves employed (rather than automating them out of existence), and that their only skill is in making toys (rather than factory building or whatever), How would Santa’s elves be able to build complex electronic toys?
