5G isn't bullshit, but it will be years before the standards are completed to do novel things, like Vehicle-To-Pedestrian (V2P) -- imagine cars sensing humans and no longer running into them.
I'm not going to be one of those "the eye can't even see 60fps" people but lets not pretend that 5g is going to be anything but an incremental infrastructure upgrade that won't affect people in a non congested area.
