I pretty much agree. With ease and ubiquity it will be very useful for some tasks ("hey honey, which of these lamps do you like better"), and for some "big moment" calls ("this is your new grandson"). So, it can be significant even without being a large fraction of overall calls. Most people like being able to get away with all those little things that the other person can't hear over a phone. Being on camera would seem more stifling/restrictive than freeing in many situations.
