In a world where we no longer have the rat's nest of complexity, we pretty much no longer need to produce code. All the software we will ever need for the next century could fit on books in one, single-floor library, if we exclude art projects like video games. An operating system with full driver support for every I/O peripheral (if those devices use standard protocols, allowing for a https://xkcd.com/927/ constant of 5), and support for every standard document format (again, assuming 5 bitmap image formats, 5 vector image formats, 5 kinds of print-ready document, 5 kinds of hypertext document…), could easily fit in 2GiB, and that would be done: everything anyone could possibly need out of a computer, apart from art, mathematics and science, for… I don't even know how long. We're still using the Latin alphabet, more or less unchanged since the late 15th century. Working technology doesn't need to change.

Being able to automatically generate large quantities of code that is worse than a good human programmer can produce is not helpful in this world you're envisioning.
