What is the typical end user? Is it you with your TV? Me with mine? My neighbor with their soundbar I can hear through the walls? The guy on the train with his airpods? There is no standard, its all over the place.

A pretty common complaint is that developers only test things on their latest generation i9, with unlimited ram, and 8k displays.
