Generally, all the code I write is reviewed by humans, so commits need to be small and easily reviewable. I can't submit something I don't understand myself or I may piss off my colleagues, or it may never get reviewed.
Now if it was a personal project or something with low value, I would probably be more lenient but I think if you use a statically typed language, the type system + unit tests can capture a lot of issues so it may be ok to have local blocks that you don't look in details.
Yeah for me, I use AI with Rust and a suite of 1000 tests in my codebase. I also use CoPilot VS code plugin mostly, which as far as I can tell heavily weights toward local code around it and often it just writing code based on my other code. I've found AI to be a good macro debugger too, as macro debugging tools are severely lacking in most ecosystems.
But when I see people using these AI tools to write JavaScript of Python code wholesale from scratch, that's a huge question mark for me. Because how?? How are you sure that this thing works? How are you sure when you update it won't break? Indeed the answer seems to be "We don't know why it works, we can't tell you under which conditions it will break, we can't give you any performance guarantees because we didn't test or design for those, we can't give you any security guarantees because we don't know what security is and why that's important."
People forgot we're out here trying to do software engineering, not software generation. Eternal September is upon us.
