The WordPress comparison holds up, and there's a detail in it worth pulling out: WordPress made sites cheap to build, but the economy grew around what comes after the build: hosting, updates, plugins, someone to call when it breaks. I think the same split is coming for vibe-coded apps. Making the app is becoming a prompt; keeping it online, patched and trustworthy for a year is still work. That's where your trust point bites: nobody hands their kid's data to an app whose maker can't say where it runs or who maintains it.
