I think this point gets lost on people. A frequent argument I see in favor of vibecoding is: “well there’s also bad engineers”. In other words, bad code is already being written, so who cares if the LLM is wrong sometimes?

The issue is that with no reins, the LLM is a fire hose of bad code compared to the garden hose of bad code orgs had before. A good engineer, with a good model and harness will produce great stuff. A bad engineer with a good model and harness will produce something faster, but it will be worse.
