Linux is a pretty standard Unix kernel clone that got traction as an x86 kernel, combined with the GNU userland and various distributions.
Git was intentionally designed to be "simple and stupid." It's extremely fast and reliable because of this simplicity, and because Linus knows how filesystems and kernel caches work.
So I agree that Linus has helped bring about some remarkable things. But it's not because he's an ultra-productive genius. He has a knack for C coding, an impatient and "lazy" attitude, and a lot of help.
And I think he belongs to this kinda older school of hacking, part of which is his rudeness toward bad patches.
The GPL is also a big part of these success stories.
