You simply cannot get widespread adoption with a name like FedNow. The American government (I know, the Fed is not the gov) will not be able to pull it off, just like they can't build high speed rail or rockets or water desalination plants.

The only way they could pull it off is to merge with and put Big Tech in charge. But that would require some even more outlandish propaganda than they have already done, to sell/dupe the American people, as well as the rest of the world, if they want to maintain reserve currency status. All while their credibility (and therefore legitimacy) is dwindling by the day.

Basically, they are fucked and their cantillionaire days are numbered.
