That's the core of situation as described in the article. I wonder how true that is, that it's faster overall than having developers build the MVP.
From what I've seen, I think developers can build just as fast, especially with AI assistance. They may not want to though, knowing full well the MVP/prototype will go directly into production.
Better to take some time to have a decent architecture early on. Product and management probably see that as a waste of time.
On the other hand, vibe coding allows the product team to make exactly what they want without having to explain it to developers. That's the real draw to this, basically a much better figma.
Perhaps there is a market for a product oriented vibe coding tool, that doesn't pretend to make code, but gives developers much better specifications while allowing the product and business side better input in the process.
