Transistors are an important, integral part of all the electronic devices we love to use every day, but how do they work? Veritasium discusses the science of semi-conductor materials, doping with impurities, gates, and depletion layers that make transistor technology possible.

So my laptop is basically an array of switches? Does that mean that if we somehow collected all the light switches in one place they could become a giant computer (powered by humans)?
PS: Veritasium sounds like Veritaserum, a truth potion in the Harry Potter series.
