Do you want to be a millionaire or a billionaire? (Featuring every YouTuber selling a 'vibe coding' course right now)

If that is true, why aren't they building these products themselves, selling them, and actually becoming billionaires?

Do people genuinely believe it's that easy to get rich just by vibe coding?
