And this is better how exactly? If you're running a business, do you not want to catch employees mistakes as early as possible? Most ideas are crap. I'd way rather they get elimated after someone spent an hour making slides than a day vibecoding a prototype.

And then there is the problem that vibecoding is addictive so the more one has done of it on the prototype, the worse one's judgement of whether it's actually something worth building...
