If that could have been achieved it would have been very profitable, too. There's no shortage of cheap, motivated interns/3rd world devs and the executive class prefer to rely on disposable resources even when it costs more overall.
The net result was always the opposite though - one or two juniors on a leash could be productive but more than that and it always caused more problems than it solved.
Seeing the same problem with agents. Multi agent orchestration seems like a scam to manufacture demand for tokens.
