> The idea of circles sounds fantastic on paper but it's simply too much work for the common user.

Google has ML based version of circle where depending on who is on the photo or whom you have added as recipient it suggests additional recipients.

To me that is a better UX.

a. They don't have to explicitly create circles.

b. If you keep adding someone new or remove someone over a period of time, the model would learn that and act accordingly.

c. If user wants to explicitly create a circle, they can probably do it as a group.
