Because you ask, here is an idea: We are still using browsers, which offer flat surfaces and sounds that everybody can listen too. 1. With 5G, one camera, two micro beamers and two sets of micro loud speakers, you can look at movies in 3D, even in a cramped place and hear beautiful sounds that people around will not hear. 2. You can send in real time 50 biological markers that are measured by the daily pill that you ingest each morning (and defecate later). This enables a health service to monitor your insulin pump as well as your tiny pacemaker and your vagal nerve to control inflammation. There are indeed other usages but I would refrain from mentioning them here.
