Envelope Protection
Allow me a moments speculation with a purpose: Crew incapacitation after depressurization.
Airbus hypothesis of the late '70s was that machinery was able to provide 'protections' that would help avoid aerodynamic stalls and other 'edge of the envelope' flight conditions. These protections have undoubtedly contributed to the industry wide massive increase in safety we've enjoyed.
Today the Aircraft (a bunch of related, communicating systems) 'knows' the cabin is rapidly climbing, the crew hasn't touched anything on the MCP for many seconds, perhaps the Master Warning hasn't been acknowledged.
It also knows where the Terrain is, what the MSA is, and the direction to lower terrain. It's capable of maintaining a safe flying speed if thrust is set to idle (spoilers.. not yet in the FBW logic?)
My point is, extending the established protections this year we could create a "Hypoxia" protection where the aircraft could fly itself if necessary with an unconscious crew to a safe altitude, equalize the cabin and fly away from terrain conflicts. All without having to reach up and kill 2 ADIRUs..
