How long the AI took

All three pieces were built by an AI coding agent (Claude Code) on Nov. 1, 2026. Times come from the session log.

News quiz About 2 min.

Writing the five questions and the quiz page. The same 3½-minute request also produced the first version of this page and a test pass on desktop and phone.

Ballpark! About 4 min.

Two minutes to write the game and two more to test and fix it. The same 6-minute request also redesigned this page and published the site.

Gap City About 26 min.

About 3 minutes reading the sources, 20 writing the 3D game and 3 testing, fixing and publishing a first version. Most of the work was deciding the budget choices and placing Chicago’s landmarks.

About 49 minutes from the first request to this site going live. That doesn’t count the time a person spent reviewing the work and asking for changes. Fast isn’t the same as checked: the figures were checked against the sources below, and they still deserve an editor’s review.
