> The productivity gains are real and large

This is also just untrue. There is a study showing that the productivity gain is -20%, developers (and especially managers) just assume it is +25%. And when they are told about this they still feel they are +20% faster. It's the dev equivalent of mounting a cool-looking spoiler to your car.

There are productivity gains, but they're in the fuzzy tasks like generating documentation and breaking up a project into bite-sized tasks. Or finding the right regex or combination of command line flags, and that last one I would triple verify if it was anything difficult to reverse.
