Why they won't vibecode everything: An anecdote

I was recently speaking to a very dear friend who isn't a de but has an itch to build, and he's been learning tools quickly, helping him vibe code fun things like a personal site, a fidget spinner that responds to music and such. The issue is that Dunning-Kruger effect catches up quickly. He now wants to build a "coding agent". The difference is that this one will be 'end to end' - you give it an idea and it will deliver the final product.
