Is it though?

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 ?

Many tools make lesser developers more productive (to a point) but they fail to improve the productivity of talented professionals. Lots of "no/low" code things come to mind. But here's a tool that made kentonv 2x productive at a task that's clearly in his wheelhouse. It seems under the right conditions it can improve the productivity of developers at the opposite end of the spectrum.

What other tools could do that?

To answer your question explicitly, we do have existing tools that help on that end, but they are nerdy and not hyped by beginners.

Type systems, LSPs, tests, formatters, Rust’s borrow checker, logs and traces, source control are examples of things that make experts go faster. This space is hardly neglected (but could always be better).

It is really nice to see LLMs helping on all skill levels.
