  1. Our reading · no longer heldThe Rails doctrine's 'progress over stability' is the one point that dated: churn is not progress, and stability turned out to be worth more.

    Recalls holdingI used to think it required more churn to get progress to stay on the leading edge of new stuff. And I wrote this before I experienced the indignity of the 2010s in the JavaScript community.
