Does crack me up what people think is new. I was emailing in the 80s. I was "using" part of the ARPANET in the early 90's when it open to a more public domain purpose. It was pretty unfunctional, pretty archaic, command dependent, not much out there. ARPA was pretty functional once you were inside the government sponsored world.
It does make me laugh at what people thought was multitasking. "No, your processor is really just concentrating on another thread." At the same time, it is pretty amazing at how much processing capability is now in 3 cubic inches.
