The bottleneck when using a "faster keyboard" is understanding. We have a tool for this in compsci. Not having to fully understand something in order to successfully exploit it is a staple of computer science; we use abstractions to help us reason at a higher level. You don't necessarily always have to understand the nuance involved in selecting a hash function just to put and get some items in a hash map. Specifically, when are these cases where you don't need to go that deep? Are there similar scenarios for ai written code?

I'm more interested right now in what does that abstraction look like for AI generated code. Is there some reasonable solution wherein a sandboxed component in the enterprise architecture has various attributes (e.g. the bytes i stuff into this file store component are always the exact bytes i get back from it) confirmed by methods other than a human reading its code? Those methods, are they cheaper, faster, safer than just having a human do it?

If your enterprise architects have to read every line of code in your system today then i'd claim your architecture practices have room to mature. What can derived from that, and in which scenarios, for the purposes of safely leveraging immutable write-only code? I'm not interested in evolving the code (lines of code spent to solve a business problem was never an asset, it was always a cost) if it wasn't hand crafted by a human, i still have the requirements so i can just regenerate the entire thing with the revised requirement.
