It is the perfect name for an industry that considers "enshittification" a serious term of art.
And I say that knowing it will absolutely rule everything in the future - I'd bet at last half of all Show HNs are vibe coded apps now. Not long ago tech was seriously talking about monkey JPEGS being the future of global commerce and finance. We've been living in unserious times for a while.
I'd feel better about vibe coding and AI in general if I thought it would lead to more people learning how to do what it enables for themselves, and actually exercise control over their devices and creativity. But as useful as it can be - and I have to concede that much at this point - it requires depending on centralized AI services and isn't much better than proprietary code in terms of defending end user rights. I fear AI driven everything will lead to more closed systems and more corporate commoditization of our data and our lives. Unfortunately from what I've seen not only do many vibe coders not care, they don't want to care and they think anyone who does care is a slope-headed neanderthal.
So yeah, call it what it is. OP's app would have just been a simple web app ten years ago, it's just a quiz, doesn't require any deep coding magic. But no one cares about anything but the vibe anymore.
