I have worked with code where 1000s of lines are very straightforward and linear.
I’ve worked on code where 100 lines is crucial and very domain specific. It can be exceptionally clean and well-commented and it still takes days to unpack.
The skills and effort required to review and understand those situations are quite different.
One is like distance driving a boring highway in the Midwest: don’t get drowsy, avoid veering into the indistinguishable corn fields, and you’ll get there. The other is like navigating a narrow mountain road in a thunderstorm: you’re 100% engaged and you might still tumble or get hit by lightning.
So I’m pretty skeptical that reviewing 2000 lines of code won’t take any more time than reviewing 200 lines of code.
Furthermore how do you know the AI generated lines are the open highway lines of code and not the mountain road ones? There might be hallucinations that pattern match as perfectly reasonable with a hard to spot flaw.
It depends on the code. If you’re comparing code of the same complexity then, sure, 2000 lines will take longer than 200.
I was comparing straight linear code to far more complex code. The bug/line rate will be different and the time to review per line will be different.

Again, it depends on the code. Which was my point.
Linear code lacks branches, loops, indirection, and recursion. That kind of code is easy to reason about and easy to review. The assumptions are inherently local. You still have to be alert and aware to avoid driving into the cornfields.
It’s a different beast than something like a doubly-nested state machine with callbacks, though. There you have to be alert and aware, and it’s inherently much harder to review per line of code.
Very far from the truth in practice, every line of code isn't as difficult/easy to review as the other.
{x{x,sum -2#x}/0 1}
def f(n):
if n <= 1:
return n
else:
return f(n-1) + f(n-2)
Objectives change; timeliness matters. The speed at which you deliver value is incredibly important, which is why it matters to measure your process. Deceptively dense is what I’d call software engineers who can’t accept that the process is actually generalizable to a degree and that lines of code are one of the few tangible things that can be used as a metric. Can you deliver value without lines of code?
This assumes that shorter code is faster to write. To quote Blaise Pascal, "I would have written a shorter letter, but I did not have the time."
> Can you deliver value without lines of code?
No, but you can also depreciate value when you stuff a codebase full of bloated, bug-ridden code that no man or machine can hope to understand.
“All models are wrong, some are useful”. What’s not useful is constantly bitching about how there’s no way to measure your work outside of the binary “is it done” every time process efficiency is brought up.
