For a while, I dutifully believed it, and would go try again, and it would be awful.
I'd then have another conversation like this, where someone would say something along the lines of, "sure, sure but this NEW model now fixes all that and is really awesome!"
I'll revisit it when I start seeing some real studies that show real productivity increases rather than stuff that just shifts the burden of broken slop onto PR reviewers while claiming awesome speed.
