Route A seems genuinely horrifying to me - maybe not for small and/or helper scripts; but for anything substantial. For anything that bites you or someone else hard when things go bad.
I don’t want a vibe-coded, mass-produced diabetes tracking app, or banking tool, or tax management software. I don’t want a vibe-coded power grid analysis software.
I don’t care if a person’s little, local scripting thing is vibe-coded. I don’t care if an artist’s 0->1 game code is vibe-coded; but that’s not what a lot of the things we’re talking about here really are.
