Why they won't vibecode everything: An anecdote

I was recently speaking to a very dear friend who isn't a dev 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. Since he stays on top of tech news, he is aware of the Claude Code leak and what he supposedly gathered from it is that Claude Code is just a bunch of .md files. (He straight up asked me "Have you heard of an md file?") So his understanding is that an agent essentially just needs to be given the right set of instructions in md files, and since no one else has figured how to do that right (until he now will), we don't have agents running end to end. Technically, you can ask an LLM to do something "for each entry made by the user" instead of us
