The mental model is still in my head, my brain is overloaded, but only from the amount of code reviews - like I said, I'm building v3 of a feature in the time it takes to build v1, but I am in a way doing 3x the code reviews going back and forth. That's the fall out of the iteration speed enabled by AI.
Between submitting PRs, getting feedback, iterating, re-submitting, repeat - there used to be breathing room. Now it's all compressed into an afternoon. Productivity is through the roof, but it can be draining.
If the feature isn't released, it's not a new version.
In the new world there is no time to put out v1 quality code and it is borderline reckless given how easily things are getting hacked now. You need to be putting out heavily reviewed code that covers all the corner cases on the first release.
There's no such thing as "v1 quality code", you just haven't finished it yet.
