After watching a sales person and a PM vibe code I’ll say that existing developers are not the initial for vibe coding. Vibe coding absolutely allows non-devs to achieve more than they previously could.
The issue is one of education, not possibility. There is so much hype around vibe coding that it has penetrated non-technical circles and given non-technical people the confidence to try and make things. The same people could use Zapier or Airtable or Tally or Retool or Bubble or n8n to achieve their goals but they didn't have the confidence to do so, or knowledge of the tooling.
