There’s a difference between vibe coding and responsible use.

There's also a difference between the occasional evening getting drunk and alcoholism. That doesn't make an occasional event healthy, nor does it mean you are qualified to drive a car in that state.

People who use LLMs in production code are - by definition - not "good developers". Because:

• a good developer has a clear grasp on every single instruction in the code - and critically reviewing code generated by someone else is more effort than writing it yourself
• pushing code to production without critical review is grossly negligent and compromises data & security

This already means the net gain with use of LLMs is negative. Can you use it to quickly push out some production code & impress your manager? Possibly. Will it be efficient? It might be. Will it be bug-free and secure? You'll never know until shit hits the fan.

Also: using LLMs to generate code, a dev will likely be violating copyrights of open source left and right, effectively copy-pasting licensed code from other people without attributing authorship, i.e. they exhibit parasitic behavior & outright violate laws. Furthermore the stuff that applies to all users of LLMs applies:

• they contribute to the hype, fucking up our planet, causing brain rot and skill loss on average, and pumping hardware prices to insane heights.
