There is no conclusive and objective evidence that static typing helps at all. Studies are at best inconclusive, certainly a far cry from confirming the superiority of static typing. Everything else is subjective. To have a recent and complete opinion about the one thing you necessarily need to have less of a recent and complete experience with another.

The benefits of masks against spreading respiratory viruses are easily and objectively proven. Completely different thing.

Well, while you're waiting for that study to ride down from heaven on a white horse clad in gold, the rest of us are going to just quietly get on with being (subjectively) more productive.
