>Still don't get the point of 5G.

You've not tried 5G UC then. I got over 800 mbps down with line of site to a cell tower in a very rural area. My grandparents were getting 10 mbps from the local WISP , I got them on T-Mobile home internet and now they reliably get 400+ mbps, usually close to 800 mbps for $50 a month.

5G, when its actual 5G (like Ultra Capacity or mmWave) and not that fake rebranded LTE "5G" is actually hugely faster.
