The amount of effort which goes into making our home computers work is absolutely incredible!
We mine the purist silicon sand we can find & extensively purify it further. We grow massive crystals from it's molten form, then slice it like deli ham using special saws.
In our cleanest & most tectonically-stable buildings we use complex expensive equipment to etch absolutely microscopic runes (mostly for memory) shaping how electricity flows through this otherwise non-conductive crystal.
1/2?
Engineers constantly seek to exponentially improve the equipment in those factories to fulfill the expectations of "Moore's Law".
Those crystal slices are chopped into squares & packaged in a protective case, connected to external circuitry via atom-thin gold wires. Then they are assembled onto circuitboards (multi-pass printed onto wood), & on inside a metal or plastic shell. Alongside screens & batteries with their own issues.
Then there's the sheer amount of software powering them...
