I think this is correct. When I was coming up in software engineering, it was fairly accepted that the "bus factor" of a project should only increase. Any kind of vibe coding makes that bus factor exactly one... and if a service goes down, you're stuck.

I can prompt a fix or a new feature, have it coded in a couple of minutes, and I have enough domain knowledge to look at a diff and understand what's happening pretty quickly. It is ABSOLUTELY faster. And if Claude goes down, I could easily keep working.
