4G was awful for watching videos. I had to use wireless as my main source of internet from 2G to 4G. Increase in speeds is better. 5G was where you could actually watch something (not in HD of course) without it buffering every 3 seconds. Like the way I used to use youtube was to download any videos I wanted to watch. That was less annoying than trying to watch them directly through the site. I would rather wait for the full download and watch it uninterrupted. 5G was my only option up until December of 2023. Well if you don't count satellite internet which is the worse option.

I think the AI shit is exaggerated. Back around 2018-2020 when everyone was hyping 5G there was a lot of "5G is going to enable self driver cars and IOT" like that was going to be its primary use. It's barely even used for that stuff. 6G will probably be the same. Machine learning is probably already implemented for network routing and optimization by ISPs. I don' think 6G will usher in a new age of AI technology anymore than 5G made self driving cars more common.
