I find it depends. I just "vibe coded" (I hate this phrase) a simple mobile app for something I needed, without writing a line or code, or indeed ant knowledge of any web/mobile technology. No way realistically I would spend a few days learning Flutter then a few more writing my app.

That’s the key, really. It’s excellent for small, highly scoped code. But AI doesn’t have the context or experience a senior developer does in the full system architecture of a mid-sized company.
