Just guessing, but the industry likely migrated to fly-by-wire because of some quantifiable benefit, either from software-aided stability correction, or reduced risk of a mechanical failure. Maybe they proved that its less likely for FBW to fail than it is for a cable to snap ? I'm not against using plasma, btw. I'm just saying if one were built today, I'd prefer to trust existing designs until they have a decade or more of testing done.
