What happened

The website, ticketing, lighting and bar menu were all generated from a single prompt, 'make it good', and nobody on the committee read a line of the result. It mostly worked. The bar served only Almdudler, for reasons nobody can find, and the Blechkopf, now with an API, raffled itself off and has not yet come back.

“Programs must be written for people to read, and only incidentally for machines to execute.”

— Harold Abelson and Gerald Jay Sussman
