No, but a lot is.
You see a version of this in every tech boom cycle, but this one is way more reflexive.
Mature technical software projects are slow moving because they have real users building other real software and businesses with them. Their engineering involves navigating the ecosystem and dep and compatibility constraints.
Any project moving super fast pumping out PRs either isn’t burdened/blessed with real usage OR doesn’t care about (reap real value from) the users it has.
Related theory is that the LLM “labs” are actually not particularly incentivized to prioritize stable API surfaces. They want machine interfaces to constantly rapidly change so that we must depend on model based natural language surfaces to navigate the complexity.
