I hate to say it, but I believe your confidence is severely misplaced. The indoctrinated airheads running the Fed are
hardly the "best minds in monetary policy." This is the same central bank that stuck its head in the sand despite clear warnings approaching the 2008 financial crisis, then proceeded to overreact to appear as if they were doing something(1).
When is the last time the Fed's spastic behavior had a sure and long-term positive impact on the economy from the average person's perspective? I specify this perspective because the macro measures used by central banks are not always accurate indicators of the general welfare. Central banks are good for primarily one purpose, and that is ensuring the economic dominance of the groups controlling them. This has been their purpose throughout history(2), and I don't see that changing now. This most recent move is at best a platitude.
All that said, I agree with your sentiment that blanket statements, especially in the highly dynamic field of economics, tend not to be accurate or helpful.

(2) Look into the history of the Banque Royale of France 1716-1720 and the history of the Bank of England up into the 18th century. The long and short of it is these banks were used as mechanisms by the elite to retain control over currency systems which would otherwise have given too much power to the public for their liking.
