I know 2 MBA types who have been in tech a long time who are currently doing a combo of vibe coding v0 style coupled with a regular LLM spitting out code (o3 pro I believe), coupled with a coding agent in slack they talk to, connected to github, both of them seem to be making considerably progress on being able to launch to a few 100 users on their own. That said, both of them seem to realize they can't scale an app without devops, so they will hit a wall there I suspect. Largely agree with this blog, but we'll see where things go with agents.
