This is the opposite of my experience since about February of this year.

"unless you're content with producing low quality work." - With the right guiding hand, it is a productivity multiplier without compromising quality. As a fully autonomous developer, it is a disaster.

Here's the rub. They produce low quality work according to your rubric. If that was the universal rubric, they would already have RL'd against it, and you'd like the work they produce.

What kind of work are you doing and what do you consider to be quality or not?

Of course don’t let me assume, maybe you have a higher quality disproof for the Jacobian conjecture you could share with the class.
