“The internet” is a > layer 2 technology, radio and TV transmission would all be layer 2 if you applied the OSI model. And layer 2 tech has rapidly changed since the initial creation of the internet.
ARPANET started off on dedicated phone lines essentially (and maybe microwaves). When normal people started using it it was mostly done on their actual phone line with a modem. Then we started getting tech like ISDN, T1, DSL, cable and, Fiber. Nevermind internal networking which went through a wild ride in the 90s before setting on the twisted pair that we have now.

My co worker that hates it is in a downtown area and that’s kinda why he hates it. 95% of the time it’s great and he gets >300Mbps with low latency. But when there’s a lot going on the network bogs down badly. Like if there’s ever a major sportsball game it chugs. Latency throughout the day is pretty hit or miss, but it’s normally fine as long as you’re not trying to play an online game.
Coincidentally my co worker that’s in a rural area has almost no issues because for whatever reason T-Mobile ran insanely good internet to his local tower and nobody is ever really on it so he pretty consistently gets great speeds. Suburbs might be good too since people are more spread out.
