What I'm missing here is a test environment. Gradual or not; why are they deploying straight to prod? At Cloudflare's scale, there should be a dedicated room in Cloudflare HQ with a full isolated model-scale deployment of their entire system. All changes should go there first, with tests run for every possible scenario.

Only after that do you use gradual deployment, with a big red oopsie button which immediately rolls the changes back. Languages with strong type systems won't save you, good procedure will.

Neither will seatbelts if you drive into the ocean, or helmets if you drink poison. I'm not sure what your point is.

I think you strengthened their point.

I don't think I did. The implication is that using languages with strong types (as discussed in the article) is not a solution. That's rubbish. It's at least part of the solution.
