Right off the bat their writing is exaggerating the realities, which makes me not want to bother reading any more.

• Dial-up connected virtually every time if you chose an ISP who’d provisioned enough modems for their customers to use.
• The “first time in history, you can exchange letters with someone across the world in seconds” was over a decade prior to that - it just cost an arm and a leg for the service to do so (something like $7-10/hr in early-mid 1980s money, if I recall correctly). And that’s just talking about commercial services available to the general public, as the universities, large businesses, and government/military that created the early networks had that ability before even then.
• One-minute video did NOT take “hours” to download unless it was in an absurdly high quality for the time - something pretty unusual because of the common speed (and storage requirement) constraints.

Yeah, maybe I’ll look at this later when my bullshit alarm settles down.
