Run three, run five. Prompt with voice annotation. Run them when normally you need a cognitive break. Run them while you watch netflix on another screen. Have them do TDD. Use an orchestrator. So many more options.
I feel like another problem is deep down most developers hate debugging other people's code and thats effectively what this is at times. It doesn't matter if your Associate ran off and saved you 50k lines of typing, you would still rather do it yourself than debug the code.
I would give you grave warnings, telling you the time is nigh, adapt or die, etc, but it doesn't matter. Eventually these agents will be good enough that the results will surpass you even in simple one task at a time mode.
