Yeah, this one is easy: I have been doing this for half a year. I have a couple of projects worked out this way, all green-field projects, code base grew from 0 to tens of thousand of lines each.

That is interesting. Half a year is not nothing and I expect it's harder to keep a project functioning when the base is vibe coded rather than having mature abstractions and architecture already.

I am still skeptical on this method's ability to deliver polished products though. I've kept an eye out on it in the OSS world and don't think I've seen big anything yet.
