Hi,
The only false idea is if one will claim that we could make flying an aircraft "100% safe" in every possible situations. Automatisms would make them "safer" in most situations... but not extreme ones.
I wonder whether it is thanks to these automatisms that the aircraft most often is near extreme situations
If the pilot do not have the FBW and an autopilot ... I wonder if by themselves they would go at altitudes and speed close to the coffin corner (extreme situation) to make their cruise if they have to handle their plane manually
