In the current era of urge to make things faster/more, that article felt refreshing. Good things take effort and time to create, and it is not something bad, it's just the way the things become good.
The distinction is between "low-hanging fruit" ideas ("Let's start a cafe!" "Let's start a WordPress theme business") and "high-value, high effort" ideas ("It's 2003. Let's build VoIP software.").
Today's narrative pushes people to try vibe code as much ideas as possible, even in parallel, but I don't think it's a fruitful approach. One should not be afraid of doing something non-typical (hard) if they belive in the idea. And if you believe, dedicate some quality time for it. If you don't believe - why bother even with prototypes?
That takes a lot of quality time to just figure out the right syntax and semantics, let alone having to figure out how all of these complex pieces fit together!
