Not sure the comments are debating the semantics of vibe coding or confusing ourselves with generalizing anecdotal experiences (or both). So here's my two cents.

I use LLMs on a daily basis. With the rules/commands/skills in place the code generated works, the app is functional, and the business is happy it shipped today and not 6 months from now. Now, as as super senior SWE, I have learned through my professional experiences (now an expert?) to double check your work (and that of your team) to make sure the 'logical' flows are implemented to (my personal) standard of what quality software should 'look' like. I say personal standard since my colleagues have their own preferred standard, which we like to bikeshed during company time (a company standard is after all made of the aggregate agreed upon standards of the personal experiences of the experts in the room).

Today, from my own personal (expert) anecdotal experiences, ALL SOTA LLMs generate functional/working code. But the quality of the 'slop' varies on the model, prompts, tooling, rules, skills, and commands. Which boils down to "the tool is only as good as the dev that wields it". Assuming the right tool for the right job. Assuming you have the experiences to determine the right tool for the right job. Assuming you have taken the opportunities to experience multiple jobs to pair the right tool.

Which leads me to, "Vibe coding" was initially coined (IMO) to describe those without any 'expertise' producing working/functional code/apps using an LLM. Nowadays, it seems like vibe coding means ANYONE using LLMs to generate code, including the SWE experts (like myself of course). We've been chasing quality software pre-LLM, and now we adamantly yell and scream and kick and shout about quality software from the comment sections because of LLM. I'm beginning to think quality software is a mirage we all chase, and like all mirages its just a little bit further.

All roads that lead to 'shipping' are made with slop. Some roads have slop corners, slop holes, misspelled slop, slop nouns, slop verbs, slop flows and slop data. It's just with LLMs we build the roads to 'shipping' faster.
