Decades long deflationary shock threatened by artificial intelligence

It's commonly billed as the single most influential position in the global economy – chairman of the US Federal Reserve. President Donald Trump has promised to announce who will be filling the role for the next four years by the time he sets off on a visit to Asia on Nov 3, or in other words any day now. Many column inches have already been expended speculating on who he might choose – a hawk or a dove – and I don't intend to add to them. But here's what is possibly the more interesting question; does it actually matter any more? I suppose it might, in the sense that any choice thought likely to be compliant with the president's political demands would be taken badly by markets, degrading a generally competent institution and haven of economic expertise.
