Linus Torvalds Answers Your Questions
Btw, it's not just microkernels. Any time you have "one overriding idea", and push your idea as a superior ideology, you're going to be wrong. Microkernels had one such ideology, there have been others. It's all BS. The fact is, reality is complicated, and not amenable to the "one large idea" model of problem solving. The only way that problems get solved in real life is with a lot of hard work on getting the details right. Not by some over-arching ideology that somehow magically makes things work.Yes, well, Torvalds is here disputing one of the main drivers of science, the motive that brought us Newtonian physics, quantum mechanics, you know, the very things he depends on via his use of microprocessor technology.If your "one overriding idea" is wrong, then certainly that'll get you into trouble, but as history demonstrates, they aren't always wrong. They are always hard to come up with, and often when you come up with them you face an uphill battle with people who want to maintain the status quo and who can't conceive of "one big idea." But eventually those ideas are the ones that cause tectonic shifts in human progress.His reference to Edison is apt. It wasn't Edison who brought us the AC motor that literally revolutionized power distribution and the whole industrialized world. It was a man who thought big, who had "one overriding idea": Tesla.
