> Now we'll have code that the devs don't even know what it's doing internally.
I think that has already been true for some time for large projects continuously updated over a long time, and lots of developers entering and leaving the project throughout the years because nobody who has a choice wants to do that demoralizing job for long (I was one of them in the 1990s, the job was later given to an Indian H1B who could not switch to something better easily, not before putting in a few years of torture to have a better resume, and possibly a greencard).
Most famous post here, but I would like to see what e.g. Microsoft's devs would have to say, or Adobe's:
Such code has long been held together by the extensive test suites rather than intimate knowledge of how it all works.
The task of the individual developer is to close bug tickets and add features, not to produce an optimal solution, or even refactoring. They long ago gave up on that as taking too long.
That's the reality from software development at scale, pretty soon no individual will know how everything works and you need high-level architecture overviews on the one side, and strict procedures, standards, tools, test suites etc on the other hand to make sure things keep working.
But the reality is that most of us will never work in anything that big. I think the biggest thing i've worked in was in the 500K LOC range tops.
As the OP outlined 10x is common place now; where as my best day pre-AI may have been 500 LOC now 5K LOC per day is routine. So a few months on a solo project has produced ~500k lines of code.
The code base is disproportionally testing automation, telemetry and monitoring systems but a lot code none the less ;) So even in a solo/small team project depend on architecture, procedures, test suites etc. over knowing every line of code.
