extremely rare rocks
Silicon is the second most common element in the Earth's crust... 90% of all rocks are some form of silicate...
Gold isn't tho
The gold involved is minuscule. So much so that it isn't really economic to strip it from the components.
Still rare rock extraction
No, gold isn't really anywhere near as rare as you've been led to believe. Just like diamonds. And no "rare rock extraction" is involved in making silicon chips. The claim carries no water at all.
No, no, they actually do use plenty of water, if I'm not mistaken, for cooling and such.
That doesn't carry it as the pipes have no bucket.
You also don't use extreme pressure.
Those warlocks do seem to experience tons of pressure from their masters to work faster though.
my guess is most modern electronics are mostly plastic by weight. oil is kinda like a rare rock? like semi-rare rock juice
a lot of electronics have a fair bit of lithium for the battery, but apparently we get most lithium from seawater. rare by concentration, but usually not extracted in rock form
so yeah rare, not really, and rocks, hardly at all...
