For flight data metrics, this makes sense, but this is significantly already happening with aircraft systems transmitting data back to central monitoring systems in realtime. Pilots can see an errant value (say a moderately high temperature somewhere) and call up an engine specialist and ask them if it's a concern and that specialist can look at a plethora of data on the plan in flight. The planes can also "phone home" and report things which should be looked over or fixed during the next downtime and maintenance organizations can proactively order parts or schedule personnel to fix issues before the plane even lands. This is all being done in the name of efficiency, but, it no doubt has positive safety benefits too. Airlines and manufacturers can already run a query like "how many hours between replacement of part X on average" and "how many hours between replacements of part X for planes which regularly fly to middle eastern countries (hot and dry)" For audio recordings, in the absence of an incident, I see no reason to do it.
