Several thoughts. People who’ve used conventional point-and-shoot OR SLR cameras wouldn’t consider the option to choose among different focal length lenses to be the same as using a true zoom lens, and more than they’d consider “digital zoom” to be an accurate description of what happens when one takes a portion of the sensor’s recording and blows its pixels up. There are other differences besides the loss of quality that comes from enlarging a portion of a digital image. For example, when one goes from a wide-angle optical lens to a longer focal length portrait or true telephoto lens, two things happen because the physics of the optics mandate it
The depth of field decreases
The nature of optical distortion changes. That’s why when one takes a selfie without a selfie stick the diameter of the forearm holding the camera/phone gets bigger, yet the entire image is in focus, whereas when a photographer does portraits he/she always uses a longer focal length lens to narrow the depth of field to just the subject, and also “flatten” the face a bit so that the nose, lips, and orbital ridges don’t look so prominent. Putting a multi-element true zoom lens into a camera phone would not be impossible, but it would be difficult, I think. Of course, Apple “fakes” some of that, with the digital blurring of the background when one uses portrait mode.
I’m entirely in the dark regarding how mmWave 5G content will be licensed. For example, Verizon has contracts with NFL Network to add LOTS of infrastructure to stadiums so that people who go to the games will be able to see individual plays from several different camera angles and positions simultaneously. Will Verizon be able to limit reception of that content solely to people who purchase their cell service from Verizon, or will the purchasing be leveraged by the price for the NFL Network subscription, regardless of which carrier one’s phone comes from. It seems likely that if it’s the latter Verizon is still likely to get its mitts in the deal, either by paying Verizon something for EVERY subscriber, or by limiting 5G mmWave subscriptions solely to Verizon network devices (which I don’t think is the case now).
But I’m blown away by those low light portrait images with individual stars highlighting the sky at dusk but gorgeous detail in the shadowed areas of faces, or the rich colors in those same faces in bright daylight images without blown-out white skies as a result.
