And that is the right assumption. Why would any humans need (or even want) to look at code any more? That’s like saying you want to go manually inspect the oil refinery every time you fill your car up with gas. Absurd.
Cars may be built by robots but they are maintained by human technicians. They need a reasonable layout and a service manual.
I can’t fathom (yet) having an important codebase - a significant piece of a company’s IP - that is shut off to engineers for auditing and maintenance.
