However, Linus’s kernel was more elaborate than GNU Hurd, so it was incorporated.
Quite the opposite.
GNU Hurd was a microkernel, using lots of cutting edge research, and necessitating a lot of additional complexity in userspace. This complexity also made it very difficult to get good performance.
Linux, on the other hand, was just a bog standard Unix monolithic kernel. Once they got a libc working on it, most existing Unix userspace, including the GNU userspace, was easy to port.
Linux won because it was simple, not elaborate.
Maybe.
Linux won because it worked. Hurd was stuck in research and development hell. They never were able to catch up.
