I saw a preview for the movie Golda. The lead looked very much like Golda Meir, and nothing at all like Helen Mirren.
And yet, I instantly knew it was Helen Mirren. And I wondered, why was that so easy?
My best guess is that we humans are very good at identifying somebody from their subtle and unique facial expressions. She didn’t look at all like Helen Mirren, but her face moved exactly the way Helen Mirren’s face moves.
As we drift slowly into the age of wearable extended reality, I find this very encouraging.
