in 10 years any phone should be able to wirelessly stream it to any monitor / tv and plenty of those will be everywhere
People who do this a lot probably just use a DV adapter (maybe it just works with USB-C, but I haven't tried it) for native apps, or casting for streaming video.
You could think this a bit further still, and have all kinds of devices offer an interface to nearby endpoints with a display or controls, establishing connectivity automatically.
