The rare stone thing would be better for nuclear power. Find lots of rare stone, put it together in a huge pile, they get warm and cause mysterious diseases.
Uranium is actually pretty common, refining out the right isotope is the complicated part. Heck there were a couple natural nuclear reactors in a place that generated power for a few million years.
Isn't uranium that's pure enough naturally to cause a reaction on its own really rare? I'm referring to the Chicago Pile experiment. It was so simple that it could have been theoretically built thousands of years ago which is crazy to think about.
Not really. Every single shovel full of dirt has trace amounts. It's just gathering enough into a pile. Like I said, nature did it on earth, before humans existed. It's weapons grade uranium that's really rare
Silicon is just the base material. The whole process involves a whole bunch of other chemicals, and some of those are made of much rarer stuff than silicon.
Sure, Silicon works as a cheap base. Boron, phosphorus, arsenic and antimony are also used in the process, though. Other elements are also finding use in the process.
There is also a minor error in the middle about the 'sigils'. When scribing process is happening, the other elements are embedded into or deposited onto the substrate between 'scribings'.
You may be confusing with diamonds. Gold is, and in fact, any element heavier than iron are pretty rare because they cannot be created by stars alone according to current models, they need more extreme and rare astrophysics phenomenons like supernova and black holes.
Gold is rare, compared to just about every other element, in accessible areas of earth. All the gold ever discovered on Earth would fit inside a 23 meter (75 foot) cube. This is about 244 thousand tons, in all of human history.
Compare this to iron, where just the United States produces 46 Million tons in 2022 alone.
There is plenty of gold deep within the Earth - it is very dense, so it sank towards the core when Earth was recently formed - but on the surface and the proximal crust, it is not found in abundance.
The form of silicon used in semiconductor manufacturing, specific formations of sand, is becoming harder to source from the environment. Silicon the element is incredibly abundant - the vast majority of all rocks on Earth are silicates - so there isn't a risk that we run out of silicon itself any time soon.
What may happen, in several decades, is an increase in price due to the need to process more abundant rocks to obtain pure silicon.
