As was already said in one of the reference videos, it's impressive what one person can do.
But the next step is to define an architecture where authors can defined/implement plug-ins with particular modular capabilities instead of one big monolith. For example, instead of front-end (GUI) and back-end (feeds), there ought to be a middle layer that models some of the domain logic (events: surces, filters, sinks; stories/time lines etc.).
I would like to see a plug-in for EMM (European Media Monitor) integrated, for instance ( https://emm.newsbrief.eu/NewsBrief/alertedition/en/ECnews.ht... ).
