I often think of how folks used to say that email was a joke and no one would ever use it!
There was quite the furor at the time once people did start using it... but most institutions, businesses and whatnot all kept doubling down about how snail mail (postal services) would never be appended in the field... which history shows they were very wrong about.
Had those same postal providers simply began providing email services... who knows how things would have gone for them.
Yeah. Also, what is they were not funded, at least to some degree, by governments. Where would they be? My guess is gone.
On the flip side though the postal service in this country does have a bunch of Web3 stuff rolling out. If my memory is correct they will essentially all become banks in some capacity and be the handlers of a 'digital currency' or digital asset that has direct USD value.
I think they have yet to settle on what blockchain to use or if building their own is a better approach. They would all run multiple nodes (much like exchanges do) but the primary node would be their own chain.
Don't quote me on any of that because its just what I can recall about the initiative off the top of my head.
