Device Quote by Linus Torvalds
“Personally, I'm not interested in making device drivers look like user-level. They aren't, they shouldn't be, and microkernels are just stupid.”
About This Quote
Source Interview: 2005 Linux Kernel Development Talk, Linus Torvalds
Microkernel designs should not emulate user‑space driver architecture; they serve different purposes and have distinct constraints.
In simple terms: Microkernels differ from user‑level drivers.
