I think he means "git" as in the git client, and "Linux" as in the Linux kernel. Coz both of them are linus' creations.
@harriskenny @kensp Well, git could exist without Linux, but at present people use Git to make Linux. I don't know if such a collaborative project could exist without the proper collaboration tools.
So if we're not including Gitlab I'm guessing people would say Linux would be a shit-show without the collaboration tools. But if we're imagining Linux surviving without Git, then I'd say the number of embedded devices, the cyber-security protection, et al. suggest to me that Linux does more work.

@harriskenny by "git", do you mean the site, or the method of collaboration, including gitlabs?
By "Linux", do you mean the kernel, or the GPL's method of allowing collaboration?
