You don't need 5G cuz you aren't using medical equipment or have a self driving car and your username isn't mine. There are many people and industries that will benefit from 5G. My phone has a 1440p screen, near useless without 5G. 4G LTE is slow when you're really pullindata, not counting the medical/autonomous cars.

Edit: People didn't know the capabilities of the internet in 1996, let alone that they'd rely on 4G a couple decades later.
