The million dollar (perhaps literally) question is – could @kentonv have written this library quicker by himself without any AI help?
I estimate it would have taken a few weeks, maybe months to write by hand.
That said, this is a pretty ideal use case: implementing a well-known standard on a well-known platform with a clear API spec.
In my attempts to make changes to the Workers Runtime itself using AI, I've generally not felt like it saved much time. Though, people who don't know the codebase as well as I do have reported it helped them a lot.
I have found AI incredibly useful when I jump into other people's complex codebases, that I'm not familiar with. I now feel like I'm comfortable doing that, since AI can help me find my way around very quickly, whereas previously I generally shied away from jumping in and would instead try to get someone on the team to make whatever change I needed.
I don't think this is a fair assessment give the summary of the commit history https://pastebin.com/bG0j2ube shows your work started on 2025-02-27 and started trailing off at 2025-03-20 as others joined in. Minor changes continue to present.

Still, this allowed you to complete in a month what may have taken two. That's a remarkable feat considering the time and value of someone of your caliber.
Would someone of author's caliber even be working on trivial slog item like Oauth2 implementation, if not for the novel development approach he wanted to attempt here ?
For the kind of regular jobs a engineer typically is expected to do, would it give 100% productivity jump ?
What other tools could do that?
