Elias smiled, tucked his notes into a worn leather folder, and labeled it with the title that would soon sit on the desks of thousands of engineers. He knew he wasn't just teaching people how to program a box; he was teaching them how to orchestrate the industrial future from the book, like sequencing The text covers the modular design of CPUs,
