All this time developers have been freaking out about ChatGPT taking their jobs when it's really politicians that should be nervous!
Inspired by your comment, I tried three versions of a moderately long prompt beginning with “Write a five paragraph speech by an American politician at the opening ceremony of a new bridge [sewage treatment plant, seawall along the ocean].

If you were to put the names of the bridge, city, etc. into the speeches at appropriate places, I don’t think anyone would guess that the speeches were machine-written.
