In my case is nearer to ∞x. I have developed an opensource Android app which has already ~200 users that I would never ever written in my whole life. Zero experience with mobile development and zero time in my free time to focus on this appropriately to at least try to learn how to do it. I know myself, I would have given up before getting the first dummy APK on my phone. And while it's totally vibe-coded, in the sense that I just prompted CC and not written a single line of Kotlin code, I put a ton of effort on it anyway, on how I want it to behave, how it looks like, squashing all the usual subtle bugs that CC leaves here and there.
