I have always struggled explaining this outlook to people. It is the default mode of modern consumers to look at EVERYTHING like a product or an "app" with a shelf life. It is normal for them to assume there will be a "next bitcoin", due to this "well this is how it works" fallacy.
Look at it from their perspective. They started on PayPal. And then Venmo came along. And now it's CashApp or Zelle or whatever. They are used to consuming "experiences", and, like locusts, flying off to the next "new thing". That is normally how the market iterates. They are PROGRAMMED to look at these things as products. Combined with their innate, human tendency for pattern recognition, it is no wonder they see things as "brands" with an inherent expiration date.
Except the Internet. The internet used to be considered a "fad", until it broke through the locust consumer midnset and established itself as ELEMENTAL to their life. That is what a well-designed protocol does. It becomes like water or love or oxygen -- nobody questions an elemental property of life; in fact they laugh at people who deny its impact and boundaries. Imagine a politician declaring oxygen a privilege reserved for "good citizens"... ABSURD!
I use the term "elemental" intentionally, because elements can't be stopped -- they can only offer the challenge of being understood.
