It doesn't replace MBA-brained bad roadmapping. Good engineering is determined more by the processes you have in place for catching something that breaks bad. The system produces good code - singular 'good' developers are great but if they're not socializing what makes them good then it's just competency. Great engineers teach and mentor and advocate for capacity dedicated to testing and health-checks.

Given the speed at which Anthropic regularly pushes updates (eg their ridiculous app versioning that's in the thousands for v4 now) I doubt they're doing anything that looks like quality processes, even AI-integrated ones other than basic code review skills.

I imagine it's as much of a mess internally as it is with any other company whose execs are concerned more with bottom-line valuation rather than maintainability, extensibility, and sustainability. Just lots of spaghetti-at-the-wall hoping that something sticks long enough to drive up the IPO.
