If you haven’t come across it already, read and marvel at this article by a Wired journalist who took a tour of a TSMC semiconductor fab.
“Every six months, just one of TSMC’s 13 foundries—the redoubtable Fab 18 in Tainan—carves and etches a quintillion transistors for Apple. In the form of these miniature masterpieces, which sit atop microchips, the semiconductor industry churns out more objects in a year than have ever been produced in all the other factories in all the other industries in the history of the world.” (h/t The Diff)
