Earlier quoted context omitted.
Absolutely what your neighbor did is crucial, but it is not a waterfall process. The problem space of "gathering facts" is virtually infinite, means relevance decisions has to start while deciding on what to gather more facts on. It is an iterative process that says "based on these facts we found, we investigated for these further facts and here why it all was important to promote them to public attention".
Absolutely, but my point is the original claim of "journalism is not our fact gathering process" is just wrong. Sure, there's a frame problem in journalism just as much as there is in AI, and sure, journalists play a (possibly outsized) role in finding contemporary suboptimal solutions for it. But even with that being the case, somebody has to go out and get information for us to talk about, argue about, rage about,…
Allow me to reword; facts are necessary but not at all sufficient to constitute journalism, nor journalism can claim monopoly on fact gathering. E.g. we have other, more formal, fact gathering processes such as science or court of law, which cannot be substituted with journalism, damages of which we see to the extent it tries to.
The firehose of twitter, youtube etc feeds already give us facts to talk about, argue about, rage about, call for more information about. And we are not in better shape for it. We cannot sufficiently convert those facts into sense. Nor those facts are always the ones we should be interested in.
That's why it's critical not to reduce journalism to fact gathering.
