If you would fire all incompetent [1] software developers, there would be almost nobody left.
[1] There is probably a more fitting word, I am just reusing incompetence here, but that is not a really fitting description, I think. I would maybe say carelessness or something like that, but a single word is not going to capture the issue accurately.
Same with pretty much any other profession. Hunting for reliable and reasonably-priced HVAC, plumbing, handymen, etc. is a part-time job.
But the point OP was trying to make is that because LLM harnesses output code that is at least better than the worst, say, 20% of developers then we should be fine with it. Meanwhile, I’ve worked in shops where you have to be way above the worst 20% in order to keep your job or even be hired in the first place. And it isn’t some crazy lose-sleep-over-it, stressful requirement. It’s just that literally if you’re not good enough your work will be identified as a liability and you’ll be let go. It’s only happened to 3 people fwiw.
