I was playing around with v0, and was able to very quickly get 'kinda sorta close-ish' to an application I've been wanting to build for a while, it was quite impressive.
But then the progress slowed right down, I experienced that familiar thing many others have where, once you get past a certain level of complexity, it's breaking things, removing features, re-introducing bugs all while burning through your credits.
It was at this point I remembered I'm actually a software engineer, so pushed the code it had written to github and pulled it down.
Total mess. Massive files, duplicated code all over the place, just a shitshow. I spent a day refactoring it so I could actually work with it, and am continuing to make progress on the base it built for me.
I think you can vibe code the basis of something really quickly, but the AI starts to get confused and trip over it's own shitty code. A human would take a step back and realise they need to do some refactoring, but AI just keeps adding to the pile.
It has saved me a good few months of work on this project, but to really get to a finished product it's going to be a few more months of my own work.
I think a lot of non-technical people are going to vibe-code themselves to ~60-70% of the way there and then hit a wall when the AI starts going around in circles, and they have no idea how to work with the generated code themselves.
Or you can get back to vibecoding after fixing things and establishing a good base. then it helps you go faster until you feel like understanding and refactoring things because it got some things wrong. It is a continuous process.
