I am sorry, but this kind of comment has become too common on this site. It underestimates the kind of code a highly efficient human being coder is capable of writing and managing over a long period of time ( which is what is required in a real job, btw ).

The only thing that I think coding agents are better than good human coders is the ability to generate a lot of usable code in a shorter period of time.

But can they maintain it over a long period of time? I highly doubt that, given the evidence that I have with me. Coding agents under-perform quite often in my line of work. They overproduce and yet are not able to cover the given requirements.

Sometimes they do 100% of the given task, but miss a slight detail ( given clearly in the prompt ), that renders their product unusable. This quite often results in a complete rewrite - consuming more, guess what, tokens!!!

So anyone who thinks that right now, coding agents can replace human coders completely, is really not working with these agents long enough or hard enough.

Once you start demanding from agents the same quality of code and the added responsibility/liability that you would associate with a human code, you will sure see the difference and I can tell you that its a lot.

I work with Opus 5.5 and Codex Astra 6 on a wide range of projects and they are found completely wanting in certain situations where a human would be more trustworthy and produce better results.
