I see symptoms of this all the time. For example, it's a weekly annoyance for folks to pop into /r/strava to showcase their vibe-coded app that uses the Strava API to do $THING. Then someone invariably points out that an existing app (or even Strava itself) already does $THING, and often it's free. I don't mean to be negative, I think it's great that people are building useful niche software and I don't blame them for wanting to share it. A significant part of the problem is that it's much harder nowadays to find "prior art" because keyword/boolean web searches have been FUBAR.
