Rather than all the conspiracy/terror theories and suggestions for Triple-armored padlocked security-clearance fingerprint double dead-man switches and remote-control robot future-planes,

I suggest that we consider the SCALE of this incident related to the amount of flights flown daily in the world, shake your head, and mourn for the victims and their families, and move on.

Psychological evaluations for pilots seems like a good idea though.
