Andrew, is that you? <grin>
Okay, I admit that much of my early OS design knowledge I learned from him. Literally, he wrote my OS design college textbook. He wrote my networking textbook too. But most of my views in this area come from me being an anal-retentive neat freak when it comes to computing. Torvalds didn't want to tackle the performance issues of microkernels, thus advancing computer science, so he just went monolithic with something anybody could have built. And like any good professor, Tanenbaum called him on it.
