Some of this is good, and some of it I feel makes some fundamental misunderstandings. The good: "tight feedback loops are really important". Absolutely. Getting feedback about a change you (as a developer) are making is key, and the longer that takes the more time is spent waiting which is annoying and concentration breaking. This is, in my experience, usually tied to the implementation of tests (read: not bloated and useless) and not really a core tenant of CI.

However, things like:

    [...] git is already showing its weaknesses. Fork-and-pull isn't the final form of development workflows.

Show that the author is perhaps conflating GitHub with Git.
