Those comparisons are incredibly mismatched. In 1980 a computer cost as much as a car, and network connections were incredibly expensive and slow. Bill Gates, child of wealth and privilege, famously had to use a shared computer paid for by his elite school because even the child of an IBM board member wouldn’t have access to a computer! The microprocessor revolution unfolded in the 80s, however, so even your timeline is off by over a decade because people paid money to get online because things like email, telnet, Usenet, and FTP were immediately useful. By 1995, the web was already multiple years into extreme growth – very little of which was directly related to selling as opposed to all of the things you could do with it. Nobody was saying you should buy a modem and sit on it before reselling it at a profit, they were talking about all of the things you could do once you had one!
Similarly, nobody doubted that neural networks were capable of very interesting things - the holdup was the level of processing power needed to run them. As soon as that changes, useful applications abounded.
Those make quite the contrast with bitcoin which has been universally available to a much, much larger population and had truly massive resources available, but almost no meaningful impact because it doesn’t give most people anything new or better. The few businesses which aren’t trying to market it and still accept it almost universally convert BTC into real currency as soon as they receive it, companies like Western Union and Visa haven’t felt the need to lower rates, and to the extent that PayPal is reconsidering screwing everyone so aggressively it’s because of Venmo and Stripe, not Bitcoin.
