alt Hacker NewsRight, I don't think you can "productively review a couple thousand" lines of code per day. That would imply that the review step for this very patch only took a couple days in total (since the core code is described as 5k lines) which is rather implausible to say the least.
Both Simon Willison and Antirez said that using LLMs helped them, so it's kind of perverse to read them and conclude the opposite.
In particular, doing direct comparisons between metrics like that doesn't work. "Lines of code" isn't a good way to measure complexity of the code, and the amount of time it takes to review the code will vary quite a bit based on the use case.
There's a lot of diversity in what kind of code people write and just because it worked for someone else doesn't mean it will work for the kinds of problems you solve. It's anecdotal evidence that someone else found it useful, your mileage may vary.
