The problem with being on the public stage, is that Every. Single. Word. They. Utter. has the ability to be reframed. With Deepfakes, they can now have words put in their mouths, in a realistic manner.
That's why so many politicians and C-suite execs are "weasely." They learn to choose their words carefully. The Fed Chair can crash the markets, by wincing at the wrong time.
I empathize with him (see what I did, there?), but he's in a position where his utterances can either do great good, or great harm.
Many of these mega-rich folks keep their mouths shut, and that's for a reason.
