I don't actually think the article refutes this. But the AI needs to be in the hands of someone who can review the code (or astrophysics paper), notice and understand issues, and tell the AI what changes to make. Rinse, repeat. It's still probably faster than writing all the code yourself (but that doesn't mean you can fire all your engineers).
The question is, how do you become the person who can effectively review AI code without actually writing code without an AI? I'd argue you basically can't.
