No. I see the risk of a vibe coder getting prompt-injected to be negligible compared to a programmer being malicious themselves, and I've been running closed source executables for decades.

In general, I find that new vibe coded (or at least AI-assisted) user-facing software tends to be good, actually. LLMs don't have a 9 to 5 job, and don't get burnt out or tired. Vibe coded software tends to have attention to detail that I don't see in human-written open source software because a human wouldn't bother.

I'm enjoying democratization of software. Maybe in a few years we will have a vibe-coded open source Windows replacement.
