The repetitive piece - the piece that needs that process-control - is moving from shipping code to its creation.

That's new. All analogies to 2022 software engineering need to be thrown out.

Software construction is now more like an industrial process, with the artisanal work shifting towards both

1. aligning what's built with what's needed (talking to customers!)

as well as

2. implementing and tuning your software construction process (ie. hi - we're Anthropic. We're burying ourselves in a mountain of code but it's okay because the fix is a second mountain of code, try some tokens the first hit's free!)

Back to my original point...

Writing code is now on the production line; making quality output demands industrial grade/scale verification (some involving humans of course).. which is a fascinating engineering challenge, and it's brand new!
