The first ARPAnet was immediately useful to almost everyone who had access to it.
Everyone has had access to cryptocurrency for over a decade, yet it still only has its original niches. This is a niche technology, not the next revolution.

As an Ethereum user, I find Ethereum useful. Maybe my experience is not unlike that of the initial ARPAnet users?
While between jobs, I have paid my rent with a blockchain-based loan. I found Ethereum to be a much better creditor than a bank.
I've quickly and inexpensively sent money to friends in other countries.

On this point, you are misinformed. There are many niches, services, and new kinds of financial primitives that have emerged on Ethereum over the past few years.
An overnight success twenty years in the making :)
