I think really high class places, hotels, restaurants, high-end night clubs, high-end Country Clubs, Corporate affairs, etc., will ALWAYS hire 'live' players (solo pianists/combos/small and large bands) but that will reduce the working musician population to guys/gals that can actually play (just like now). IOW, if you are a professional-level player like, say Rory Hoffman, MACHINES WILL NOT REPLACE YOU! JMO, of course.
