It's an excellent essay, and the Fortran community owes you a major gratitude for promoting these issues. But surely there loops can be safely parallelized if the iterations do not interact, e.g. per-element array arithmetic, and a compiler ought to safely identify such arithmetic. Also, isn't your employer promoting do concurrent as a method of GPU parallelization? Has this been controversial within Nvidia?
